[I was hung up with some beggar in the sky.]

Charlotte in 'Blue Charlotte' seems to be the same as the Charlotte in heaven in 'Early Bird Cafe' (Sad Clowns and Hillbillies):
'Charlotte asked me where I'd been with her jade and ivory eyes
I told her I'd been hung up, with some beggar in disguise
Well she laughed like temple bells
Kissed me on the cheek and said:
"You know it's hard to be alive sometimes...
But it's easy...
To be dead!"

Charlotte is in a good place.

I read at Wikipedia about the song:
Mellencamp also told Gardner about his favorite part of the song, saying: "I love the last part of it where she says, 'She asked me where I'd been, and I said I was hung up with some beggar in the sky.' I thought that was a beautiful line. 'I was hung up with God – I was trying to find God' is what he's saying. I guess you guys figured that out, right?"[21]

That's strange, because the line isn't 'some beggar in the sky' but 'some beggar in disguise'.
Can you explain, John???

And the beggar in disguise has a connection with Cinderella:
Cinderella is a kind young woman who lives with her wicked stepmother and ugly stepsisters. They abuse her and use her as the housemaid. One day Cinderella's stepmother and stepsisters refuse to help a beggar at their door, but Cinderella offers her food and drink. The beggar woman is revealed to be a beautiful fairy in disguise, who then secretly helps Cinderella for her kindness.

He sings also at Ghostbrothers of a Darkland County:

Hello I'm new on this forum. I'm living in Amsterdam. I'm a fan of Bob Dylan and I think the lyrics of John Mellencamp are like a 'Plain Spoken' Dylan so to say. I know they are friends, and the ego of Dylan is not huge so it is possible dat mr Dylan is writing lyrics for mr Mellencamp! My English is not perfect but I can read it perfectly and I am a good interpretator of lyrics if I can say it myself.
I like the songs Ghost Brothers of Darkland County very much and they brought me here. From the other songs 'Blue Charlotte' moves me a lot. 'What if I'm came knocking' is lyrically fantastic. I am stil discovering the songs.
