Many years ago, when I was working the nite club circuit, I would use a special style for the Pink Panther, mute everything but the finger snap and bass, hit an Am and walk through the audience with a wireless mic singing Fever to the ladies and flirting with them. They loved it! Not sure if the boyfriends and husbands did, though.
I only did this with a few songs, and most of the time I remained at the Keyboard.
PSR-S950, TC Helicon Harmony-M, Digitech VR, Samson Q7, Sennheiser E855, Custom Console, and lots of other silly stuff!
