Hey Dave,
Missed that piece of news. Yes, sad indeed. What a genius. Years ago when I was hanging out in the studio with Wayne Henderson (trombonist for Jazz Crusaders), I met Bobby Lyle. Another incredible key board player who Wayne helped bring up. Bobby said Oscar was his main inspiration. In particular his ability to play a different rhythm with his left hand and another with his right?! I'm probably not describing this correctly ,but I think you know what I mean.
Things are going great here bro. Will PM some more info later.
Safe travels to LA when the time comes.
