Live Aid - critics and journalists

Is there anyone here that knows the details of the polls that were voted by critics and journalists, that had Queens performance voted at Live Aid as the greatest performance/gig/show?
I know there was two in 2005 but I'm not sure which ones they were. Or if there were any others as well.

(Not polls where the public voted)

What exactly are you asking?

Which company or whatever it was that conducted the polls.

One was BBC, if I rememeber correctly.
