What happened to Queen: In the 1970s -or In the 1970s: Queen - DVD?
Does this DVD contains any new footage, like some new part of some new concert or something like that? link
I don't get what you mean by "what happened to it?".
Do you mean you think it didn't get released? It did! It's available to buy just now online, as well as from a number of record stores.
I didn't buy it, because these DVDs are usually cheaply done, and most feature the same snippets from old interviews. If you've heard Roy Thomas Beaker say "throw in some more Gilileos" once, you've heard it a million times. And I'm fed up looking at Paul Gambaccini.
But it's roughly £6. The price should be a a hint as to how crap it will be.
