I feel very mixed about these guys. On one hand, they were nice to work with and all of my guests raved about how much they loved them. On the other hand, they completely ignored our list of favorite artists and songs. We made the list based on their online song list, so I don't know what happened. Fortunately, they managed to get the first dance and father-daughter songs right.
If you like their online sample list, and don't care very much about specific songs, then they are a great band to pick.
