We used the Dave Blakely Duo for our recent wedding in Napa Valley. We had them learn a few new songs, and asked them to played as the whole wedding congregation sang a hymn. I was a little nervous about those things, but they did a good job. T...hey also were perfect for the cocktail hour, and were nice to my little nephew who was very interested in their instruments.
They were a little late coming in at one point in the wedding, and email communication was only okay. Still, they were very nice and probably would be even better if it was not a destination wedding, and we had been able to meet before hand. I would recommend them to other brides!
