Many years ago the 30 quid i earned at a pub gig, really supplemented my income.
150 gigs a year and a full time job was great.
Ive gigged hard for nearly 40 years.
Ive also bought a lot of gear with that money, which I couldn't have afforded without the gigs.
Then, 21 years ago I started playing solo gigs
My wife had left me and I needed something to keep me occupied
I made a fortune for a couple of years.
I thought I had to charge the same as other solo performers or I would be taking work from them.
My Police tribute hardly ever made any money a nd usually we were out of pocket after hotels etc but it was fun
As I get older I really dont need the money and so dont really charge as much as I could for my duo
I still do charity gigs for free.
I've never really thought of playing for free, the way you do Chris, it's an interesting conundrum
