As is mentioned in a thread on small talk titled "Midnight Special DVDS", those are available too...as a subscription. Don't know how many you have to buy before the one(s) with Gord show up at your gate though.
The 1979 Soundstage Special was shown on a lot of PBS stations. I saw it twice, years apart,(yes, the 2nd time as a rerun) on WGBH out of Boston.
Great pics Peter Bro!
