There is a band that I like that I have not yet talked about here, and they are Me First and the Gimme Gimmes (MFatGG).
I first came across them when I was looking for "Sloop John B" by the Beach Boys. It turns out that MFatGG did a cover of the song, and I found that. It was very funny and it's still in the rotation.
The band is kind of a punk ska, and only does covers. One of the covers they do is "Eastbound and Down" from Smokey and the Bandit, which was one of my favorite songs as a kid.
All of their other stuff is good, and I highly recommend them if your in the mood for some new takes on familiar music.
I woudl link to their sales site, but the band page is not loading. So go to Fatwreck.com, and look for them yourself.
