I would love a series of documentaries where Brian and roger (and john ideally - no chance, though) go through the entire back catalogue and review the music and provide insights into how it was created and background stories. kinda like they did for Bo Rhap on the GH1 DVD and in the BBC special on BR, and perhaps will do on the future ANATO DVD
i can't imagine for a second that they would actually wish to take on such a tour de force, but it would be a great thing.
They could do an edited/abridged version for TV or the mass market (i.e on the hits), but for us serious fans, I would expect us to want to all about the more obscure tracks like MOTBQ, TFFMS, Prophets Song, Innuendo etc. and in more depth
that would be a seriously interesting documentary
Though I think we will never see it, it is nevertheless, a good call. However, with a bit of digital magic, we could still include the old Fredmeister, (just like the Beatles included Lennon in their Anthology).
Perhaps we a QZ could make our own!
