I was playing my new PSR740 for the Xmas party at the local skating rink. Ionly had it for 2 weeks and was still finding my way around it. The lighting was bad and I while I could play the tunes OK, I couldn't see all the buttons for selecting voices, styles etc. Also the cables I had were too short and I had difficulty in hooking it up to the PA system. If that wasn't bad enough, half a dozen keyboard players came out of the woodwork to talk to me. Funnily enough I was able to keep playing while having a half dozen conversations.
Another time I played the piano at a concert and in shifting the piano on to the stage they managed to disconnect the pedals. That was a dry performance!
