The "Queen Talks" snippet that you heard is a nonsensical (but still very funny) mish-mash of all kinds of stuff. There's bits from the One Vision sessions, a little bit from the Innuendo EPK, loads of stuff.
The Queen for an Hour thing is a interview for the radio they did in early 1989 (shortly before doing the video for I Want it All, I think - thats what they say in the thing anyway). It's a good listen and it's been on here a few times.
I wouldn't call it official, but I have loose standards. Like - if it's only available in one country, I call that shithouse. Still if it's reasonably easy to get, then yeah - I wouldn't put it up.
Aaannyway, if you can't find this anywhere on here I've got it.
