En abril de 1967, una banda británica llamada Procol Harum emergió en el panorama musical, liderada por el carismático Gary Brooker. Brooker era un talentoso pianista y vocalista, conocido por su habilidad para fusionar el rock con elementos de música clásica. Le acompañaban el letrista Keith Reid, el guitarrista Robin Trower, el baterista B.J. Wilson, el tecladista Matthew Fisher y el bajista David Knights.
No tardaron mucho en dejar su huella en la música. En mayo de 1967, lanzaron su primer sencillo, "A Whiter Shade of Pale", una mezcla hipnótica de rock, pop y música clásica, adornada con el órgano de Fisher y la evocadora letra de Reid. La canción no solo se convirtió en un éxito mundial, sino que también estableció a Procol Harum como pioneros del rock sinfónico. Hasta el día de hoy, es considerada una de las piezas más icónicas de la música moderna.
A medida que avanzaba su carrera, la formación de Procol Harum sufrió varios cambios. Robin Trower dejó la banda en 1971 para seguir una carrera en solitario, siendo reemplazado por Dave Ball y posteriormente por Mick Grabham. A pesar de estos cambios, el núcleo creativo constituido por Brooker y Reid mantuvo cohesionado el grupo.

Our local picture house was showing a Batman movie
You see this guy fly up in the sky, thought to myself, 'Why shouldn't I?'
So I bought a pair of wings, went up upon a wall
I was about to jump into the air when a guy from the street called
He said, 'Hey wait a minute! Don't you realize the danger?
What do you think you are, some kind of angel?'
I considered for a minute, realized he spoke the truth.
For the barbells on my eyelids only emphasised my youth
and the sawdust in my plimsolls means the same to him as me
But that's neither here nor further, so I spoke considerately
'Now if you understand just what I'm trying to say,
whatever you do, don't grin, you'll give the game away!'
By now a crowd had gathered and it seemed that all was lost
In the anger of the moment I had diced with death and lost
It seemed to me the time was right so I burst into song
In the anger of the moment the crowd began to sing along
I could not see a way out of this predicament
Just then a breeze came through the trees and up in the air I went
I must have flown a mile, or maybe it was eight
Thought to myself pretty soon I'd hit the Golden Gates
Just then a passing bird for no reason I could see
took a peck at my wings and that was the end of me
I went down, hit the ground faster than the speed of sound
Luckily I broke no bones only tore my underclothes
