Got this from the Head Heritage website:
"Some good soul (possibly with links to the old Tyne Tees TV station) is in the process of uploading every episode (around 100 in total, I think) of The Tube: https://www.youtube.com/user/davisxl1/videos They appear to be from the studio master tapes, too."
The Bunnymen appeared a few times and there's an interview + video of Mac promoting the September Song solo release. S03E10 about ten minutes in.
Peter Cook taking the piss out of Bring on the dancing horses is good too.
