The only mistake I made was not being a piano player. This was in the early eighties and I had begun a big New Years party. I got half way through my first set and the electricity went out. I was screwed because the only thing available was a God awful broken down upright piano with half the keys missing. I did the best I could, but never was a piano player and had to rely on left hand block chords. I never felt so much pressure in my life. The juice was off for 30 minutes, but felt like hours.
