The Hard Rock Cafe in London may have some SW mementos as the cast hung out there during filming (I stupidly walked past the place but forgot to go eat there when I was in London...DOH!)

Go to Abbey Road and get someone to take a picture of you crossing the street Beatles-style. :-P I managed to do that while I was there, but I missed the studio tour. :-( The London Symphony Orchestra recorded some of the the SW soundtracks there I think.

The place I stayed was a nice Bed & Breakfast but I can't recall the name. I'll post the name if I can find it.
