what’s a song cover that you think is better than the original?

Johannes Brahms' Variations on a theme by Haydn.

Sergei Rachmaninoff's Rhapsody on a theme of Paganini.

I haven't gone through all the responses in this string but....

Elton John: Lucy In The Sky
Sinead O'Connor: Nothing Compares to U
Tom Jones/Art of Noise: Kiss
Eva Cassidy: Somewhere Over the Rainbow
Joe Cocker: With a Little Help from My Friends
Jimi Hendrix: All Along the Watchtower
Aretha: Respect
Patti Davis: Because The Night

Of course tons more, but I'd have been remiss if I didn't stick my two cents into this thread!   -Wayne
