Playing with others is a lot of fun. I let them lead the way. At times I feel over my head but that is the best way to learn. The guys you are playing with will help you fix your mistakes.

In terms of songs, hard to say. Depends on what you all like and what you can play. And if you have to leave a section out because you can't make the chord, don't worry about it. Jump back in when you can. They won't stop playing. It's all supposed to be fun. A great time to have a few drinks and chuckles with your buddies.
