The other side of “Wow, that’s a great cover of that song!”
A common thread that I’ve realized is that if the song has biographical or personal opinions in it, it likely should never be played or sung by someone else.
Yesterday I watched the making of the the Rock Aid for Armenia version of Smoke on the Water, featuring Brian May, David Gilmore, Tony Iommi and others, along with Richie Blackmore. And I realized that more doesn’t always make it better. Not only did Blackmore not play live with most of the others, but there was another singer, don’t remember or care who it was, who sang along with Ian Gillian.
The song MUST always include Blackmore, and no one but Gillian should sing “We all came out to Montreux…” I remember when Gillian left Deep Purple, there was another singer, again don’t know or care who it was, that replaced him. When I heard him sing the opening lines, I thought; “NO YOU DIDN’T” and skipped to Blackmore’s solo just to see if he still had it. He did.
Old Man should never be sung by anyone but Neil Young and Southern Man can only by done by Young or CSNY.
Layla should never be played or sung by anyone but a 1971 pain and angst filled Clapton, driven to stunning brilliance by Duane Allman.
Bad Company can only be sung by Paul Rogers.
Lay Down Candles can only be sung by Melanie Rush backed by the Edwin Hawkins Singers. And only played with as the full version with the opening poem.
The Wall can only be performed by the original and true Pink Floyd. So sadly any song from the albums should ever be played live again.
CSNY is allowed to perform Woodstock because Joni Mitchell was inspired by Graham Nash.
No one, anytime, anywhere is allowed to sing Somebody to Love or *White Rabbit" except Gracie Slick!
Edit: Any Black Sabbath song, originally sung by Ozzie and OMG! NOT DIO!
No Doors song should ever be performed by anyone but Jim!
