Any Sounboard of Queen before 1984?

i'm looking for but nothing, just audience recordings which are not to much nice to listen or sounboards after 1984.
so, that's all.
any links will help me.

PS: i hope that those recordings will be in Flac format( or any loseless compression audio)

Why soundboards? Why not very good/excellent audience.Audience recordings are much better because you get the right feeling.

What soundboards exist AFTER '84 (other than the released albums?)

audience sources are not good enough like a sounboard.
i just want to hear them, not all those screams from the audience

Then you just have to stick with studio albums.
