I threw a surprise 25th anniversary party (40 people) for my wife. Mark was the perfect choice and it worked out better than I could've hoped for. We had AC issues and had to switch rooms. In 10 minutes Mark moved and was playing the perfect songs to get the party going again. The variety of songs he knows is unbelievable. The entire party sang along to all the favorites like American Pie, Sweet Caroline, etc. He was gracious enough to let people come up and sing. He did every thing he could to ensure we had a fabulous party. We booked a 3 1/2 hour party, we were having so much fun, he stayed an extra 2 hours. If you want a fun Party then you must use Mark Burnam.
