Helter Skelter is at the top of my list too.
The acoustic version of Bridge Over Troubled Water that Jon and Richie did in 96 is incredible - almost as good as the original. That's hard for me to say too since I am a big Simon and Garfunkel fan.
Jon's version of Hearts of Stone gives me chills and I think I like it better than the original.
Just Like a Woman is excellent - but when comparing to Bob Dylan's voice.....nuff said.
I think Richie does Midnight Rider better than the Allman Brothers (now I'm ducking).
Sylvia's Mother and Levon were both done perfectly (in my opinion) but both of them stuck quite closely to the originals.
As you can tell I like a lot of Bon Jovi's covers. I think for the most part they do a cover song justice. Some bands just murder them
