Complete rainbow show 11/20/1974

Hi, I guess most of you have the " Live at the Rainbow" video from 1974, but you know, some of the songs are cut like "father to son" and "keep yourself alive", and I wanna know if there's a complete film of this show. So if you know something, please post it. Thank you.

I would imagine that there is a complete video, or that there was at some point....

From Queenconcerts.com -

"Professional recording should exist in the archives. 50 minutes were released on VHS in the Box Of Tricks. Full versions of Son And Daughter and Liar exist and are being spread as 'Adelaide 1974'."
