We don't have a "band day", but we do get together outside of the band setting. We'll hang out and watch movies, go get dinner, go see other bands play. I think what he's getting at is if you want your band to have longevity, you all need to get along with one another. You should treat each other more like brothers and less like co-workers.
I've been with my current group for almost 1.5 years so far, seems to be working out well. *knock on wood*
