I don't, hence damn old age.
For the show at the Boch Center last year, Buddy said he was basically sitting next to me, so when I got there, I say to the guy sitting there, Hey Buddy! To which he says hey what's up! I start talking to him like I know who he was, and he must've been thinking who the fuck is this guy?
Shortly afterward I feel a tap on my shoulder and it was the real Buddy!
