Luyện nghe bài hát Knockin On Heavens Door

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

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