OK, so I went to a jam session over the weekend... first one in decades. I had a blast, but one thing became glaringly obvious. When the host turned to me and said, "What do you know that you'd like to play?" ... my mind went blank ... slightly because I was put on the spot, but MOSTLY because I realized I don't actually *KNOW* very many songs outside of the worship stuff I do regularly. I was able to fake it for most of the stuff they knew, either by following the changes or by recalling the tunes once they started playing them, but... So... to help fill up my bag of tricks... besides Mustang Sally, what classic rock tunes (let's say late 60s through early 90s) should I bone up on and have at least a good general knowledge of?
