This is almost a direct rip-off of the old VH1 show "Bands Reunited". That had a guy tracking down each band member individually and, quite often, literally stopping them in the supermarket to talk about the band.
he'd then invite them to a location for an interview with the other band members and offer them a chance to play a one off gig to a small group of fans in the same building.
either way, it was an entertaining show and when it worked, and all the band members agreed to play, it was great - the kajagoogoo gig was good
so it certainly might be worth a look.
