Couple of things come to mind.
One old Town Hall we played at had a sloping stage and in those early days of rock'n'roll, virtually every song was an assault on the piano. So there I am pounding away on some Jerry Lee Lewis tune and the piano gently starts to roll down the slope towards the front of the stage. It took me and the bass player to halt its progress, otherwise there could have been a nasty accident.
Another time, when I'd just got a Hohner Pianet, we were playing at a function and a couple of recording co. reps were coming to check us out. Now, the volume, or swell, control on the old Pianet was by way of a knee-operated lever suspended from the underside of the keyboard. Well, I was so nervous that my knee started to tremble uncontrollably and the volume was suddenly all over the place. Couldn't have done any harm, though. We did get our contract with CBS.
