The last band I was in (several years ago) was a 5 piece. We learned 45 songs and were just starting to get ready to play out. The drummer's wife got pregnant, and wouldnt let us practice there anymore. He didnt want to tote his equipment around to practice, so we just folded it.
It's hard keeping all the personalities, musical tastes, and skill levels in order.
I wouldn't mind jamming with some people again though. I would have to retool. I literally only own two acoustic guitars now.
