I was in the congregation at a July wedding, in a very small, urban, solid stone church. The air conditioners were turned off becaust you couldn't hear the priest when they were on. The young couple wanted to do everything in a big way, so they hired a brass quintet. The volume pasted us flat to the pews, man and boy, before the actual wedding even started. By the end of the ceremony it seemed like it was taking forever to get the congregation out of the building. I seriously considered passing each of the musicians a fiver (I wasn't rich then, either) to change the recessional to, say "Tiger Rag", just to get things moving.
