It depends on what version you're listening to. The album version was originally on their Fool For the City album, and Nick Jameson was playing bass. If you're listening to the Foghat - Live version, Craig MacGregor is playing bass. I don't know all of Craig's equipment when they were doing the Live recordings, but the black block Fender Jazz will be forever etched in my mind. Foghat as a band had many different bassists over the years. You can check out
