Here's my thoughts for what its worth. I think the "live" part of your act puts you on a higher level than this musical dribble. It's like the Cha cha Slide. No one cares if you sing or play it, they just want to dance . When your doing something "Live" it makes you unique.
Most parties that I bring the keyboard to are me "live" for the first part, when things are just getting started and they might actually pay attention, and then I jump into DJ mode with a few live things thrown in.
My other thought is with all the musical talent available in this country why did the Charity Committee choose this no talent one shot wonder to preform?
