FI mentioned again last night that he's thinking about having his bach party the night before the wedding. There's a band playing that follows (Roger Clyne), and they're playing in Minneapolis that Friday night. Our rehearsal is at 6 PM, dinner at 7 PM, bowling from at least 7:30 - 8:30 PM. The band goes on around 10:30 and usually plays until 1:00-1:30 AM. He would then have to come back to St. Paul to sleep. The ceremony starts at 3:30 PM on Saturday. FI isn't a heavy drinker, but he will probably have a few drinks. All of the groomsmen will be with him. His plan before he found out about the concert was to have the bach party on that Thursday night, as some of the GM are from out of town, but will be there Thursday night.I don't think this is a great idea, but I don't want to start things off with "you can't do that." Am I over reacting? What would you do?
