Rather than a authored bio, or another live CD or DVD (unless its pre-1980!), I would like Gordon to do something like Neil Young has done - see trailer:
its like an updated version of Telescope
or I would settle for something like Ian Tyson did, when he filmed visits with a half dozen of those who assisted or influenced his career the most. Remember how he chatted with each one of them (including Gord) and also jammed?
anyhow, that is my latest 'I Have a Dream' speech
btw, i have not seen the Young film
