I found a VHS tape I made of the Freddie Mercury Tribute concert - recorded off Canadian TV.
I assume the quality is crap with bleeds and whatnot (although i did have a "great at the time" 4-Head Mitsubishi VCR.)
If anyone (preferably in Canada to save on shipping) is interested in it - I can send it out so long as you promise to share.
If it's already common - I would assume that what's out there is in better quality.
