Years ago, back when our local "prog-rock" station, WXRT, didn't suck, they'd occasionally play Patti Smith's cover of Debby Boone's "You Light Up My LIfe."
8 or 9 years ago, I managed to find an MP3 of it, but lost it in a hard drive crash somewhere along the way. Luck was a lady today; I threw an old mix cd into my car stereo and what should appear? Yep, Patti in all her glory. I've put it in my Boxnet on the side for anyone who wants to download it.
