Found this video of Sonseed lipsynching "Jesus is a friend of mine" via Maggie Dawn's blog, but a post describing the phenomenon which is Sonseed is here. There is a brilliantly unconcerned innocence about the whole thing. This isn't post-modern irony, it's just people oblivious to how naff they might look enjoying themselves.
Terrific. Apparently you can download the whole album here. I haven't.
