I remember some years ago, playing at a party in Breax Bridge, LA. Doing a swing song and a really large lady was dancing with a man. I was set up right next to the dance floor on the same level, no bandstand.
This lady had a REALLY big back side! With each "swing" it was getting closer and closer to my keyboard. Finally she swung backwards within an inch of my setup, and I just STOPPED the music, and announced, "Let's have some fun; everybody change partners!" It worked as she moved away and found another victim.
There have been other close calls, including a time where I packed up and left a place when the SECOND fight broke out on the dance floor. Too close for comfort there. The owner followed me to the parking lot and asked why I was leaving early and I told him my equipment was worth way more than he was paying me. Bless his little heart, he paid me anyway!
