I think I was four years old when John Prine & Bonnie Raitt sang this phenomenal song together in 1974 on 'Streetlights.' The lyrics suit a female singer, though there's more behind the song.I've heard Prine describe the woman in the song as a lonely, bored housewife whose husband doesn't pay attention to her anymore. I've also heard he wrote it to talk about a woman convicted of first degree murder and sitting on death row in Alabama asking for clemency in the form of an 'Angel From Montgomery.'Since I believe taking life is amoral, the death penalty is too broken and fallible (hundreds of exonerees because of mistaken eyewitness identifications, coerced confessions, and advances in DNA, toxicology, and forensic science), and its cost vs successful execution ratio is so weak, I like Prine's second explanation better. I hope her appellate angels at least got her death sentence commuted to life without parole... I played it with a capo on the first fret, experimenting with that octave range, and changing the lyrics slightly so that it's a man on death row. It's also a great song sans capo for a jam session if someone is sporting a C harmonica. Bonnie plays it best with a capo on the second fret and a little draw on the A string, which is a version I'll try to post later.
