Don't know about the groupie thing!?, but did read (think it was in the Q Prog rock special) an article with Scott Gorham of Thin Lizzy that when they were touring with Rush in the '70's while he was in the dressing room backstage doing the whole rock star thing Geddy Alex and Neil came into the room and started acting out parts from some American/Canadian (?) comedy show leave it to beaver (again not sure of title, don't have my Q mag handy) in front of Scott and his female companions!.
Sounds to me like the whole groupie thing was not on their list of priorities!.
