Free jazz and humor...

It's fun to listen to old known tunes off the key in free jazz or jazz-punk versions.
I've heard lots of USA patriotic songs off the key performed by Carla Bley and in addition to that, always wanted to listen to the following songs off the key and funny and compiled the list of 'candidates' of my amusement:

1. Bruce Springsteen -- Born In The USA.
2. Paul McCartney -- Let it Be
3. Stairway to Heaven
4. Paul Simon -- Graceland. 
It's "off key", not "off the key".  Kinda changes the meaning...

This great album with Brave Combo backing Tiny Tim is full of fun ditties.
