My bro' also tells the story of the Rolling Stones being in Wayzata or Excelsior Minnesota down at the water front when the carnival was in town (actually, at the time I think the carnival was a permanent fixture in this particular park).

Anyhow, there was a developmentally disabled guy that went by the name of Mr. Jimmy who was "on the scene". As the story goes, Mick Jagger was sick (or his girlfriend was sick I think) and he was standing in the line at the pharmacy and struck up a conversation with "Mr. Jimmy". The rest is history... (see "You can't always get what you want...)

I met Mr. Jimmy once on the street there because my brother had befriended him...

(I know... I am dropping names... but I thought it was a cool story and I liked the Stones even more afterwards...)
