Well, i visited QOL Page and "discover" an intresting section about the LIVE band, yes i know we have queenlive.ca but is nice to see the official page shows this kind of information (Mainly from the forthcoming Greg`s Book)
http://www.queenonline.com/en/the-band/live/queen/1970/
In the 1976 section we can read this about Hyde park gig:
"This show, one of the many milestones in Queen's touring life, was
filmed in it's entirety, but has yet to be released officially"
Yes i know maybe there isn`t nothing really new there,but i think it`s a step on the right side!
Cheers!
