Queen - Atlanta 1975 existing (?) tape

Hello everyone, I found 4 websites informing about the list of available Queen bootlegs and they included concerts from Atlanta 12/03/75 show. On two of this sites the traders offered them for exchange, unfortunately the pages are quite old and hence my question. Is it possible? Someone could contact them?

You, perhaps......?

It's actually Bradford '74 but in a higher generation

OK, any way to get this or it's the same as this? http://www.queenzone.com/forums/1450148/bradford-1974-new-transfer-of-a-very-old-trade-tape.aspx

it is the same source and the version of your link is an upgrade over the fake Atlanta 75 recording.
