09.08.1986 Knebworth Park
Rainbow 19.11.1974 - recently found in Queen archives, would be great to see
Rainbow 20.11.1974 - probably only parts from the official video still exist
Rainbow 31.03.1974 - there is no evidence that more than 2 songs were filmed
Budokan 1.5.1975 - there is no evidence that more than 3 songs were filmed
Hammersmith Odeon 24.12.1975 - there is no evidence that the final encore was filmed, I think it wasn't
Earls Court 7.6.1977 - why not release both nights ?
Spring 78 - what do you think exists ?
xx.xx.79 - there is a huge chance that complete videos of Brussels, Rotterdam, 3 nights at Paris and 2 nights at Budokan still exist
1980 - Paris exists, maybe even the whole concert
Caracas 27.9.1981 - a better version will appear here in (probably) January 2011
03.11.1982 - probably doesn't exist
1984 - first song(s) from Brussels and Milan exist
11.5.1986 Wembley first night - what makes you think that a complete video exists ?
27.7.1986 - the video is crap, I wasn't able to watch more than 5 minutes of it.
Knebworth Park - probably only the second half exists filmed by the DoRo crew
