Best attempt at upscaling this to 720p (which didn't turn out that great). Produced during the time that guitarist Rik Emmett was doing his solo career after leaving the band in 1988. At that time, he was very much estranged/not on speaking terms with the other two members (drummer Gil Moore and bassist Mike Levine). At that time, it looked highly unlikely that the band would ever get back together again.
It's an interesting look back (as each member talks about both the good and then the bad times that ultimately led up Emmett's departure, the acrimony resulting from lawsuits, and how each member felt about the possibility of ever reuniting (and at least in Emmett's case, get back on speaking terms with Levine and Moore again).
A few years later, many attempts were made when there were plans to have the band inducted into the Canadian Music Hall of Fame. Emmett's brother who was fighting cancer, asked Rik before his passing, to at least talk to his former bandmates (that life was too short to remain bitter). That (plus others who did what it took to get those conversations and meetings happening) led to the three talking and ironing out those past unresolved differences where they also appeared together on stage again to accept their induction. This also led to them performing together for the first time since 1988 at two festivals in 2008; the Sweden Rock Festival and Rocklahoma.
The ending part of this documentary (and each of their words spoken including Emmett saying "never say never") is most poignant given their 50th Anniversary Reloaded tour.
