There is a reason for that, thanks to the always informative Bob B's extra liner notes, he is actually AWOL. He's not there, Bob reckons that he was just booked somewhere else, as he was a busy man in those days and was late for the session. Burrell is only on half the BACK AT THE CHICKEN SHACK/MIDNIGHT SPECIAL sessions, I never realised this either from the original version or notes, just thought he was quite quiet.
Bloody 'ell! I never realised that, either.
Oh well, I've got McMasters of both, so I guess, now I know the secret in the sleeve notes, I don't need to buy the RVGs
Hurray!!
