In July 1967 the band got their first #1 hit "A Whiter Shade of Pale", co-written by Brooker & Reid, becoming one of the first real "symphonic rock" songs. A lot of albums and singles were released afterwards, but never enjoyed the success of their first single.
The line up for their first single was:
Gary Brooker: vocals and piano
Matthew Fisher: Hammond organ
David Knights: bass
Ray Royer: guitar.
Drums by session drummer Bill Eyden.
Procol Harum re-formed in October 1991 and recorded "The Prodigal Stranger" with this line-up:
Brooker - vocals and piano
Keith Reid - words
Fisher - hammond organ
Dave Bronze - bass
Mark Brzezicki - drums
Jerry Stevenson - mandolin and guitar
