My version of the verse you are looking for came from Mum.

Late last night well I had a funny dream.
I dreamt that I had died.
I went up to heaven but they wouldn't let me in
So the other place I tried.
There was the devil all a-standing at the gate,
He looked at me with a grin
And said, "Hello Peter, my old mate, why don't you come all I'm?"
Come inside etc.
You went up to heaven and St. Peter told you twice
They don't have folk singers in at any price!
So come in why don't you, and all the demons cried
Don't you know this is the place for all folk singers
Come inside you silly fellow come inside!
