My husband's jazz band used to do a lot of wedding receptions. Urgh. We would go to the bride's mothers house with all our Real Books and my husband's mind, which is like a library of jazz, and still, the same old set lists over and over and over and over.....its one of tje reasons we stopped fulltime music and know only do it for the love of the thing...its no fun unless its fun, if you know what I mean!
We had our music all picked out partly on the basis we loved it and partly because we knew our friends, most of whom were also jobbing musicians at the time, would also enjoy it! In the end we eloped and didn't have our playlist at all, but it was wonderful chosing it.
