Talking about the all night concerts, I did some of the first all night concerts back in the 60's with this little harmonium, and I also had saxophone taped delays.
I remember lying on the floor of the living room with headphones on when I was four or five years old, listening to the Saturday Night Fever soundtrack.
But I would lie on the floor and analyze everything. I'd listen to all the strings and the background vocals on the Saturday Night Fever soundtrack and try to pick out the different instruments.
I play a percussion instrument, not a musical saw; it needs no amplification. Where it's needed, they put a microphone in front of the bass drum. But, I don't think it's necessary to play that way every night.
Before the group left, Gary asked for my phone number, and the next day he called to ask me to dinner that night. I had no idea he was married, but I found out that night.
