Pumping Iron Lyrics – Starlight Express
Pumping Iron Lyrics
Oh boy - here comes trouble. It's the reigning champion.
COACHES
It's Greaseball, it's Greaseball, Greaseball the diesel.
Choose me Greaseball, race with me.
DINAH
Back off girls - he's mine.
GREASEBALL
Here comes the diesel train
With its steel refrain,
Hear me knocking.
The diesel's on its way,
It's gonna win the day,
Hear me knocking.
Listen to the chatter of the diesel force,
Generating twenty seven hundred horse,
Camshaft rolling while the rockers rock,
Hear me knock.
See me hustle,
Feel my muscle,
Pumping Iron.
Trying to build my body,
Trying to lose my mind.
See me straining,
I'm in training,
Pumping Iron.
I'm a diesel engine,
I'm knocking, I'm knocking, I'm knocking,
I'm Pumping Iron.
COACHES
Well he's the one they'll choose,
You know he just can't lose,
Hear him knocking.
There ain't another rig
That's even half as big,
Hear him knocking.
Everybody's gonna say "that train is smart",
The mighty diesel engine is a work of art.
The undisputed leader of the Rolling Stock,
GREASEBALL
See me knock.
GREASEBALL AND COACHES
See me hustle,
Feel my muscle,
Pumping Iron.
Stretching my bullworker,
I'm heaving on my weights.
See my flex my delts and pecs - I'm
Pumping Iron.
I'm a diesel engine,
Hey, I'm knocking, you know I'm knocking, said I'm knocking hey-
Heading for the rally (heading for the rally)
Gonna win the first race (gonna win the first race)
I'm gonna run the longest (the biggest and the strongest)
I'm knocking, said I'm knocking, you know I'm knocking.
Well - I'm so beautiful -
I'm PUMPING IRON !
Song Overview

“Pumping Iron” is the swaggering Act 1 workout from Andrew Lloyd Webber’s Starlight Express - first released on the 1984 Original London Cast Recording for Polydor, with music by Andrew Lloyd Webber and lyrics by Richard Stilgoe. On most editions it runs about 3:17, produced for the original album by Andrew Lloyd Webber, with Alan Shacklock credited on later remasters.
Personal Review
This track is all engine-noise and grin, and the lyrics lean into that bravado. The band hits a rockabilly strut, brass snaps, and Greaseball preens like a locker-room champ. Quick snapshot of the plot pull - a diesel bruiser boasts his way toward the big race, using gym talk and engine parts to sell the myth. The lyrics repeat like reps, which is exactly the point.
Song Meaning and Annotations

Placement matters. In the original London flow, “Pumping Iron” arrives in Act 1 as Greaseball talks up diesel muscle. Later versions sometimes shuffle running order, but its function stays the same - a flex before the flag drops.
Musically it’s a theatre-pop hybrid: rock pulse, show-brass hits, keyboards doubling hooks, plus the period-favorite harmonica color that runs through Starlight Express. You can hear how the score sits between West End balladry and glossy 80s radio.
Context keeps evolving. Recent London revivals have retooled the sound and promotional singles, but the scene still plays as a character billboard - fast, loud, funny.
Culturally, the show’s outsize spectacle grew from an abandoned animated-trains idea that became a roller-skating arena musical. That grand scale sits behind this compact brag-song - a quiet plot engine disguised as a gym selfie.
Here comes the diesel train - With its steel refrain
The lyric stacks material images - steel, pistons, camshafts - and translates them into gym talk. It isn’t subtle, which is why it works: Greaseball reduces romance and racing to horsepower.
Generating twenty-seven hundred horse
Horsepower becomes character design. Greaseball’s specs read like a poster in a depot - numbers as swagger. The show plays that chest-thump for laughs and rivalry.
Camshaft rolling while the rockers rock
Mechanics as poetry: the camshaft times intake and exhaust; “rockers” rock. It’s a mini-lesson in engine cycles masquerading as a dance cue.
Stretching my bullworker
A 60s-80s fitness staple sneaks into the lyric. The Bullworker - an isometric exercise device invented by Gert F. Kölbel in 1962 - was still a pop reference when the musical opened in 1984. Perfect for Greaseball’s preening vibe.
German-language productions keep the boast but tailor phrasing and crowd call-outs, underscoring how the song’s gym-and-grease grammar travels.
Creation history
Starlight Express opened at London’s Apollo Victoria on March 27, 1984, with Trevor Nunn, John Napier, Arlene Phillips, David Cullen and Martin Levan shaping its look, orchestrations, and sound. Sleeve notes on early editions highlight live capture in April 1984 with studio finishing at Audio International.
Verse Highlights

Verse 1
Greaseball enters like a sports ad: stats first, chest later. The groove is mid-tempo, letting consonants punch - diesel, steel, rock - while backing vocals sell his reputation.
Chorus
“See me hustle, feel my muscle” lands like a flex on beat two. Short phrases, tight rests. The hook repeats to mimic reps in a set - simple, sticky.
Bridge
The rally chants kick in and the ensemble stacks lines. It feels like a weigh-in before the race, not the race itself - hype by design.

How to Sing?
Range and type. Greaseball is written for baritone up to A4, often cast with a rock-leaning voice. That puts “Pumping Iron” comfortably in speechy mix territory - chest-driven, clean consonants.
Breath and groove. Keep phrases short and snappy, breathe between slogans not words. Treat the chant lines like counted reps: release the tail, reset, hit again.
Staging realities. If you’re skating, breathe at the tops of glides, not at the arrivals. Clip the K in knocking late so it sits on the backbeat, then get out of its way.
Songs Exploring Themes of bravado and competition
“Greased Lightnin’” - Grease. Another garage-born boast, but dirtier and looser. Where “Pumping Iron” uses gym talk and engine parts, “Greased Lightnin’” revels in custom-shop fantasy. Both brag, one struts, the other leers.
“King of New York” - Newsies. Different stakes, same chest-out energy. The tap-and-brass joy makes triumph sound communal, while “Pumping Iron” keeps the spotlight on one diesel star. Confidence versus cockiness - close cousins, not twins.
“I Am the Very Model of a Modern Major-General” - The Pirates of Penzance. A patter-song of credentials rather than muscles, yet the game is similar: pile proof on proof until the room submits. Greaseball would approve of the technique, if not the wardrobe.
