Sid & Susie is the stage name for the collaboration between Matthew Sweet and Susanna Hoffs. An unlikely combination - a guy from the Athens, GA music scene, a gal from LA - but it has been a combination that has worked thus far, in almost every circumstance. I am a fan of the two of them separately, and I am a fan of them together.
Here they are, performing the song "Different Drum", itself originally popularized as a cover. The song was written by Mike Nesmith of the Monkees, and performed by them and others before The Stone Poneys got a hold of it and made it a classic. Susanna Hoffs has at least as perfect a voice for these sweet lyrics as Linda Ronstadt did back then.
