It has to be Beatles, in sincerity. However, Shatner’s has a so bad it’s good quality. It’s just absurd how he could do this and no-one told him it’s not a good idea or they did and he didn’t listen. I can see how Futurama based Zapp Brannigan off him. I would have done the more absurd cover of Mr Tambourine Man, but the rules stated no Dylan, so anyone curious do check that out.
