Yes, as you may have read today, I have agreed to do a cameo at the Keith Emerson tribute concert ins Los Angeles on May 28th.  I am so busy trying to finish the massive UK box set that I will only be able to play two or three pieces in the show, but it seems like it will be a great concert, with or without my participation.
Let me say that losing my friend and teenage hero Keith has been a big blow, and I am just at the beginning of publicly acknowledging what he meant to my early development as a keyboard player.
