For your wedding, sickness you want to choose a band which 1) you like, patient and 2) is qualified and experienced. It’s pretty easy to tell what you like, online but how can you tell if a band is qualified? Ask the band one simple question: “Can you wear tuxedos?” (It doesn’t matter whether you want them to wear tuxedos or not.)
Most couples getting married prefer bands to wear tuxedos. As a result, any band which has played any number of weddings at all, will own tuxedos. If a band hasn’t performed at enough weddings to have met this demand, they are not qualified to perform at yours.
