Not as far as work product.
I think I mentioned a while back that I was at an amatuer gangbang in ATL once that he also attended. It was a dom/sub thing with her blowing a bunch of strangers while blindfolded. It was all going well until her dom fisted her while holding a yellow tennis ball in his hand. Things came to an abrupt halt and we just all slinked out of the room with our clothes half on.
I didn't have much interaction with South. He was not the host and there were no cameras involved. We spoke a bit about LA porn and he just seemed like a crackpot hater. Years later I confirmed my impression. Not a night I will forget for a long time.
