Firefly has a dedicated following and there are many filk songs written about it. This funny, wry and witty song is a takeoff of the song from the seventh episode of Firefly called "The Ballad of Jayne Cobb". “The Man They Call Joss” is written and performed by Bedlam Bards who have released an entire album paying tribute to Firefly titled “On The Drift”.
Here is a description of their group from their web site, bedlambards.com.:
We're a musical group with two-and-a-half members; that is to say, usually there's two of us, but sometimes there's three. That's a picture of us over to your left. The grey-haired guy with the guitar is Hawke, and the dark-haired fellow with the fiddle is Cedric. Pleased to meet you.
When people ask what kind of music we play, we often say Celtic, but in fact we play "Renfolk Music," that unique blend of Celtic, English, Scandinavian, and American folk music mixed in with period tunes from the Renaissance and Middle Ages that rubs shoulders with the occasional incognito rock song at most Renaissance festivals. And we have a lot of fun playing it.
