Depends what you mean by performing. The bassist is Dave Swift. Look him up, he’s played with pretty much everyone. He’s played with Jools Holland’s band for decades. Touring all over the UK and Europe in the process. He doesn’t jump about, or entertain; that’s not his job.
If you don’t like something, then don’t watch it or listen to it. Nowadays you can watch practically anything you want, when you want, so put on something you enjoy, because for every dissenting voice on here, there’s probably hundreds if not thousands across the country who did enjoy it.
