Amazing video of Prince debuting "Purple Rain" that he doesn't want you to see

Footage from the August 1983 concert at Minneapolis' famed First Avenue club when Prince debuted the magnificent 13-minute original version of Purple Rain – with an additional third verse – that was later edited and overdubbed for the Purple Rain album. This was also guitarist Wendy Melvoin's first performance with The Revolution. Watch it now before his lawyers have it yanked again!
