I thought Angel from Montgomery was a Bonnie Raitt song that Prine covered. I always liked how he sang from an old woman's perspective and didn't try to change the gender like a lot of artists do. Then I found out that it was actually his song, which makes the gender thing even cooler.
It has always been one of my all time favorite songs period, but now I can also put it on top of my favorite Prine song's list.
