For reasons that aren't quite clear to me now, I've had a desktop post-it saying 'Kirk "Sweet Life" Israel from a dream in april 2006'. I'm not sure if I wanted to tell people about that as a nickname, or what, but here is the dream as then transcribed, so I can at least put the post-it to rest:
I had an odd dream last night. Dizzy Gillespie was giving some kind of concert playing multiple pianos at once, big stride piano stuff. (yes I know that wasn't his primary instrument.) Something happened to him and he wasn't able to finish, so they did some kind of operation to me that copied his skillset so I was able to take over the show... finishing up Bach's Toccata and Fugue in D minor he had started (don't know what happened to the stride piano stuff) in front of an audience on these multiple pianos, but they were specially rigged so that they had some organ keys as well. It was very athletic, moving from piano to piano, and my general memory of the piece helped keep things moving as I read the sheet music, though my ability to play piano like that was new from the operation.
Afterwards there was an audience Q+A though most people were hoping to have asked a Dizzy a question, not me.
Finally some guy was encouraging me to take a middle nickname for myself. He explained that back in the day, talented performers would take a name that implied their ability to put themselves on easy street, though recently the practice had fallen out of vogue because people didn't want to tempt fate that way. So I chose the name Kirk "Sweet Life" Israel.
