After listening to this, it seemed to me like the lead guitar player just went off on his own, changed keys, etc. on his lead solo, until the accordion player tried to rein him back in. Wasn't crazy about that part.
The bass is very good, pretty Grand Funkish in parts. The singer's dancing at the beginning threw me off, though. It looked too much like one of my daughters waiting for a sibling to get out of the bathroom.
