Thank you! Don’t know how I missed that one! 
Resurrecting this thread before it decomposes, I just spent a bunch of time on YouTube finding covers of Jambalaya by Hank Williams. I found some interesting covers by an old John Fogerty band (really sounded good), Brenda Lee, the Carpenters (!), and Elvis!
My wife asked me what I was doing. I said I’m reading a thread on this forum about song you like so much you want to hear all covers of it. I’m thinking Tower of Song.
She says: “Bruce Willis with All along the Watchtower.”
I’m going, like: [man, what the fcks going on with my wife? googling-googling-googling.]
“I don’t get no hits on ‘All along the Watchtower’ ‘Bruce Willis’.”
She [googling]: “Under the Boardwalk”.
Me, youtube:BruceWillis Under the Boardwalk . As expected, it’s horrendous.
Is it because she’s pregnant again, or what the fck is going on in my home? Do you think she is one of them?
One thing that has turned me off a few arrangements of “Rhapsody in Blue” is an almost burlesque-type exaggeration of some wind instrument riffs (lots of wah-wah-wah, for instance). I figured it was just latter-day fooling around until I heard an old recording with Gershwin on piano and, I think Paul Whiteman’s orchestra. It was the most tarted-up version I ever heard. Sometimes the composer isn’t the best judge of how to interpret the work.
The Chambers’ Brothers long version of “Time Has Come Today” is still my favorite, but the Ramones and Joan Jett have also done good ones.
Jetboy Jetgirl. ( I have no idea who the original is by) but a VGF of ours made a CD of all the covers of this song and we listened to it for a 6 hour car ride.
( The ride back we wanted to throw him out the window, but changed the cd instead.)
The CD was comprised of maybe 15 songs total.
