I just watched a fabulous documentary on Queen, currently on iPlayer. It was all filmed around when they went on the 77 USA tour to promote News of the World. I dearly loved the band back then! There are some really interesting old clips - recording the album, mixing it, John Deacon actually speaking! Freddie behind the drum kit (er, not exactly playing!) and Roger with the Red Special.
Well worth a watch if you like Queen at all and haven't seen it. I was a MASSIVE fan for the first 7 albums. I still think that they are all superb.
