I can tell you about the Party Boys because I saw it. It was Joe & some Australian musicians on one tour. The Australians included the late Dragon singer Marc Hunter(although he was actually a New Zealander), and guitarist Kevin Borich. I can't remember the year - it may have been 1986. So it was one tour. If there was an American equivalent of the Party Boys I don't know the details (Also remember the first time I saw Joe his band was called the Creatures From America).
