I'm going to take a page out of my buddy John's book and post a link. Just two. Not going crazy.
There's this band called Flight of the Conchords from Australia and well - just watch the video.
There's also a kid's band in New York that have a fairly polished sound and a fairly polished video on youtube as well. They call themselves Care Bears on Fire - what could be cuter that 12-year-old punks?
