A whole bunch of musicians, most famously Lady Gaga who was pretty cool (I actually didn't believe it was her at the time, but she had basically gone out of venue to have a couple drinks and soon said venue was slammed and she was whisked off to the side bar (closed that day)). Couple of former KMFDM members (then Slick Idiot) hung out with then-gf and I for a while. Met a number of famous golfers as well, but was too young to really remember/care.

If "seen" in close proximity is your only criteria, Bill Clinton, Shinzo Abe, a bunch of more minor politicians, a handful of actors, etc.

I had a fairly random life.
