One of the areas of music that I love most is the marriage of music and comedy. I credit one of my mentors, Syd Kessler with teaching me that an open mind towards style of music really opens a lot of doors when it comes to serving comedy...music from all corners of life and weird cross-mutations of styles. You've got to have big ears!
Also, it's great to work with singers and let them get outside the conventions of great pitch and great time and help them develop characters in their interpretation of a song. Sometimes cheesy can be very good!
