the songs that weren't played live.

B sides and Flash Gordon Don't Count. Queen +P.R and Solo tours count. o.k? i'll start
Queen 1~
my fairy king
the instrumental version of seven seas of rhye

note( though jesus and the night comes down weren't ever recorded live there is proof they were played)
next person do queen II!

I think lazing on a sunday afternoon, seaside rendezvous weren't played. Do the bbc versions count as live?

Lazing wás played, Seaside not.
But there is another topic on Queenzone.com that covers this question completely!
