when in rome - promises

Shellshag is one of my favorite local bands and this morning while at work , When in Rome came up on my OMD radiostation and it was the song "promises" which was a song I knew! why? because Shellshag covers it! It never occurred to me that it was a cover, not sure why since they cover a lot of awesome songs like Liz Phair's "fuck and run". Both the original and the cover are both great and I'm glad to finally know who sang it first!
