Everything Trevor said are the major differences, plus
Album :42—starting with ‘soul love’ you can hear Edge singing in right channel then B sings ‘so long, Angel of Harlem' solo
Single Mix :42 ----starting with ‘soul love’ there is a background voice (sounds like Bono) softly doubling Bono all the way through ‘so long, Angel of Harlem’
This is done the same way for the repeat of this verse.
The shorter fade out on the single version cuts off a tiny bit of Bono's ad lib.
Even so, they're really alike.
