What Songs Do You Have Several Renditions Of?

If you always buy the latest release by Lionel Richie, or own several CDs by Thelonious Monk, you have multiple reditions of a lot of stuff.
Cheers.

"Gentle on My Mind"- 3 versions, Campbell/R.E.M./Hartford; Hartford's the best. "Wichita Lineman"-Campbell; love R.E.M.'s cover.
"A Hazy Shade of Winter"- toss-up b/w S&G's original and the Bangles' cover.
"Galveston"- I have Glen Campbell's version on LP. R.E.M. has a snippet on YouTube that I would love to have a complete recording of.
"Alabama Song"- London Sinfonietta and the Doors (still one of my favorites from them).
"Mack the Knife"- London Sinfonietta and Sting

J.S. BACH- Art Of Fugue- harpsichord, string quartet, organ, piano, guitar, orchestra...
J.S.BACH- Toccata and Fugue in D-Minor BWV-565
I.STRAVINSKY- FIREBIRD, RITE OF SPRING
VIVALDI- La Straviganza
BEETHOVEN- #5, #7, #9

Lots of jazz standards, but for rock music, the song with the most takes in my collection might be The Kinks' "You Really Got Me".

I own versions by

The Kinks (3), the original and two live recordings, plus

Mott The Hoople
Van Halen
Sly & The Family Stone
801
13th Floor Elevators

There might be another couple rattling around that aren't coming to mind, as well.

Wayfaring Stranger - also done by Joan Baez in Sharon Isbin's cd.
