I've played drums for about 45 years now ... used to play Friday nights in a rock band, Saturday nights in a country western band and typically had a Sunday gig (wedding, party, etc).    Paid for a good part of college that way.   It was a good while ago too.   Generally, just a hobby now, but back in the day, I made some pretty good money.  I did purchase an electric set a while back so I didn't drive my wife totally crazy ... still have the acoustic set too though.
