Let's see... much later than most of you, but that's not surprising. I am going to guess it was around 1980, because it was at my cousin's apartment, and my son was about 4 at the time. A friend of my cousin's came over with her guitar, and sang several songs by John Prine. It was some years later, that my sister gave me a copy of Prime Prine, and since then I've collected a few more of his albums, including one where he collaborates with various women artists, like Dolores Keane and Iris DeMent, called In Spite of Ourselves. Angel from Montgomery is not on that CD but it's one of my favorites (the album, and the song).

I haven't gotten to see him live yet, but my sister has, and she was blown away by his guitar playing. Says he's even more impressive live than in recordings.
