George Michael's amazing MTV unplugged version of Freedom! 90
youtube.com
I once heard John Landis say that he had to record the singing from Aretha Franklin and James Brown live on the set of The Blues Brothers because they never sang a song the same way twice. After watching this performance, which I missed when it was originally on, I think George Michael was the same way.
MTV Unplugged is something that really should have been saved.
I guess it's all YouTube and TikTok videos these days, but I'd still like to watch a whole show like that all in one go, like we used to back when we had to watch these things on MTV or buy them on VHS.
It's a different experience.
I read that no live version of the solo at the end of "Comfortably Numb" (and certainly others of theirs) is identical.
