Procol Harum at the Wiener Konzerthaus

Mick Grabham on vocal harmony, and Chris Copping

Alan Cartwright in his habitual jacket from that era. Note the Copping tambourine in the background

Mick in mid-solo and remarkable shirt

Good detail of BJ Wilson's kit and typical grip ... relatively muted shirt ...

Alan with his Fender bass, also contributing vocal harmonies

Moments of abandon from Grabham and Copping

Side-on view of Mick and his Les Paul

Nice mood shot of Procol's bass department

Professor Copping at the Hammond ... presumably a C3 though it's not easy to tell ... in another great period shirt

Another shot of guitarist and organist ... this is an unusual set, containing no photos of Gary Brooker
