Luyện nghe bài hát Knockin On Heavens Door

"Knockin' on Heaven's Door" is a Bob Dylan song from 1973. The
have been doing it now and then since at least 1988.
something about the version that kinda confuses me... See,
the official Dylan sheet has two verses:
Mama, take badge off of me
I can't use it
It's dark, too dark for me to see
I feel I'm knockin' on heaven's door
Knock, knock, on heaven's door...
Mama, put my in the ground
I can't them anymore
That long black cloud is comin'
I feel like I'm knockin' on door
Knock, knock, on heaven's door...
Though I know Dylan often sings a third verse live:
Mama, the blood from my face
I can't see it anymore
It's a feeling that I just can't
I feel like I'm knockin' on heaven's
Knock, knock, knockin' on door...
in every IG version I have, Amy sings the following third

Mama, this blood from my face
I can't see the walls
Six horses coming to carry me away
I feel like I'm knockin' on heaven's
Knock, knock, knockin' on door...
So, I don't whether Amy re-wrote Dylan's third verse, or whether
it's from some Dylan version I don't know. I'm trying to say is
that I don't know whether to attribute the "six white horses" to
or to Amy.
To further matters, I've got one version that features a
FOURTH verse, sung by Michelle Malone. This verse both the
meter and the rhyme (ABBB in favor of ABAB), so I'm willing to
bet it's just Ms. Malone improvising...
Mama, take chains off of me
'Cause I don't want anymore
They're getting too damn heavy, I'm crawling the floor
I feel like I'm on heaven's door
Knock, knock, on heaven's door...
Oh - BTW - the first who asks me about the "Guns-n-Roses"
will feel my wrath...
-Vic.
