Hmmmmm. Perfectly adequate rendition, nothing to object to, and no reason to be impressed. I've heard it played as well as that at local jam sessions by scratch bands.
So what makes it worth watching?
Sad to relate, for most I imagine that it's the bass player's cut off shorts. I note that the rest of the band are wearing normal jeans so it's clearly not a particularly hot night where they are.
Far from being a sexist post, this is intended as an anti-sexist post. It depresses me that she attracts attention not for her (adequate but unexciting) bass playing or singing, but because she shows her legs.
