The Original from "Rainbow blues" coined, how generally known, by Ian Anderson from Jethro Tull. The song you can find as a bonus on remastered album "Warchild", released on 11th October 2002 by Chrysalis. Totalling on this release are 7 bonustitel, which were not included by the original from 1974.
The original song is a bit slowlier but, from my point of view, in its musical structure more versatile. The coverversion is fitter for nowadays. It must be pointed out the little bit modified lyric. You can find it at the end. The differring
passages of the lyric are underlined and bold.

Rainbow blues

And when the rain wasn’t made of water
And the snow didn’t have a place in the sun
So I slipped behind a rainbow
And waited till we had done.

And when the rain wasn’t made of water
And the snow didn’t have a place in the sun
So I slipped behind a rainbow
And waited till we had done.

Through northern lights on back streets ---
I told the coachman, `just drive me on,
It’s the same old destination
But a different world to sing upon.’’
So he threw back his head and he counted.
I got out about five to nine.
And I waved at the stage door-keeper ---
Said, ``mister, get me to the stage on time.’’

And when the rain wasn’t made of water
And the snow didn’t have a place in the sun
So I slipped behind a rainbow
And waited till we had done.

I packed my ammunition.
Inside the crowd was shouting, ``encore’’,
But I had a most funny feeling ---
It wasn’t me they were shouting for.
So when the tall dark lady smiled at me
I said, ``oh, baby let us go for a ride.’’
And we came upon two drinks or four
And popped them oh so neatly inside.

And when the rain wasn’t made of water
And the snow didn’t have a place in the sun
So we slipped behind a rainbow
And lay there until we had done.

Let me pack you deep in my suitcase.
Oh, there’s sure to be room for two ---
Or you can drive me to the airplane
But don’t let me catch those rainbow blues.

And when the rain wasn’t made of water
And the snow didn’t have a place in the sun
So we slipped behind a rainbow
And lay there till we had done.

And when the rain wasn’t made of water
And the snow didn’t have a place in the sun
So we slipped behind a rainbow
And lay there till we had done.

And when the rain wasn’t made of water
And the snow didn’t have a place in the sun

And when the rain wasn’t made of water
And the snow didn’t have a place in the sun

Rainbow blues

Through northern lights on back streets ---
I told the coachman, `just drive me on,

But a different world to sing upon.’’
So he threw back his head and he counted.
I got out about five to nine.
And I waved at the stage door-keeper ---
Said, ``mister, get me to the stage on time.’’

Oh but the rain wasn’t made of water
And then snow didn’t have a place in the sun
So I slipped behind a rainbow
And waited till the show had done.

I packed my ammunition.
Inside the crowd was shouting, ``encore’’,
But I had a most funny feeling ---
It wasn’t me they were shouting for.
So when the tall dark lady smiled at me
I said, ``oh, baby let us go for a ride.’’

And when the rain wasn’t made of water
And the snow didn’t have a place in the sun
So we slipped behind a rainbow
And lay there till we had done.

Oh and when the rain wasn’t made of water
And the snow didn’t have a place in the sun
So we slipped behind a rainbow
And lay there till we had done.
