Knockin' On Heavens Door(ska)

I heared that there is a ska-version of Knockin' on Heavens Door but couldn't find it. So here is a possible version of it:

main riff:

e|--x--3--x--3--x--2--x--2--x--0--x--0--x--0--x--0--|
B|--x--3--x--3--x--3--x--3--x--1--x--1--x--1--x--1--|

It sounds good with some light distortion.
You can also put in the solos of the version of Guns N Roses.

Here's the lyrics:
Mama, take this badge off of me
I can't use it anymore.
It's gettin' dark, too dark for me to see
I feel like I'm knockin' on heaven's door.

Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door

Mama, put my guns in the ground
I can't shoot them anymore.
That long black cloud is comin' down
I feel like I'm knockin' on heaven's door.

Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door
Knock, knock, knockin' on heaven's door.
