I've been playing the drums off and on since I was about 12. I'm now 57. I'd like to start playing again but haven't had much time to work on chops or tunes or anything. I reached out to an ad in Craigslist for guys looking to jam on a semi regular basis. They've circulated a song list and the jam is this Saturday. Today I sat down to listen to the tunes and see if I could play them at a reasonable level. Some I could do ok and others were a total failure. Here's my question. Should I just let the guy know that I'm far more rusty than I thought and back out or should I just go and give it a shot?
