Hey Terry..........I too am a guitarist/preformer. I stopped playing live 3 years ago. I teach guitar and bass today.

I spent about 4 years (1977-1981) selling bootlegged band t-shirts and jerseys up and down the East Coast.
I made so much money my mom thought I was dealing dope! Got arrested a couple of times, roughed up by Jackson Browne's Road Crew (he took the bootlegging personally......can't say I blame him today) and had one hell of a good time.
I saw about 2/3rds of the bands you had stubs for. The Doobies were the best act for selling tees.
I worried when I applied with the NYPD that the arrests would preclude me from joining, but they took me anyway!

Those were the days!
