Did y'all know that the Doors' "Alabama song" was written by Kurt Weill? So that's a cover version, too.
Is Bowie's or Iggy's version of "China Girl" the original, and which is the cover version?
Elvis Costello does a darned good version of The Animals' "Don't let me be misunderstood". At least as good as the original.
Patti Smith's version "Gloria", with "In excelsis Deo" beats Van Morrison's original hands down. 'Jesus died for somebody's sins, but not mine!'
Other good cover versions:
Simple Minds does a pretty decent take of Peter Gabriel's "Biko"
Marianne Faithfull did a pretty good job out of the Stones' "As tears go by"
Both Johnny Cash and Nancy Sinatra had good covers of Bob Dylan's "It ain't me, babe"
Dexy's Midnight Runners: "Jackie Wilson said" (Van Morrison)
Satchmo's verson of "Mack the knife" (Kurt Weill, again)
Baccara did a deliciously bad version of "Light my fire" (The Doors), replacing Ray Manzarek's keyboard solo with a flamenco guitar solo. It's so spectacularly bad that it's good.
Nina Hagen's version of "My way" (Ol' blue eyes) is almost as good as The Sex Pistols' version
Then we have Bob Dylan's "Blind Wille McTell" which really is the old classic "St James Infirmary"
Both Janis' and Miles' versions of "Summertime" (Gilbert & Sullivan) are just great
Softcell's version of "Tainted Love" is at least as good as Gloria Jones' original version and beats Marilyn Manson's version every time.
I can't decide whether Miles' or Eva Cassidy's version of "Time after time" (Cyndi Lauper) is the best. They're both great, though.
Bruce Springsteen's live version of Edwin Starr's "War" is every bit as good as the original
And Jeff Healey does a decent job with The Beatles' (or rather, John Harrison's) "While my guitar gently weeps"
Yes, I'm a music nerd. Why do you ask?
