I suppose this might count:
I hung out at Corey Taylor's house (Slipknot & Stone Sour singer) on New Years one time. He was playing a show with DumFux at a local bar we frequented and invited everyone in the bar over to his place (probably 30 or so people by the end of the night). He seemed to be a very down to earth person. My friends and I were big fans and in star shock the entire time lol.
another time, most likely not "legends" per se, but one time some friends and I went to KC to see a band, and for one reason or another the show had been cancelled. We went wandering around town on foot hitting various bars. We run into these guys on a street corner and they are asking if we know where some place is good to eat. We explain that we are don't know we are from out of town looking for a place too. We all decide to go into this bar & grill near us and they invite us to eat with them. Turned out while talking to them they are the band Bango Tango. A band many of us probably don't remember from the 80's. I think they had like 1 hit during their heyday. They were still very much doing their thing, very friendly and funny dudes.
I met Bruce Campbell once but it was at a horror convention so not sure it counts but it was up there on my list because he is awesome. He seemed like a pretty nice guy.
