If we are going to veer off into lame cover versions, we MUST mention William Shatner, which, unless I missed it, no one has mentioned him. I will, however, give him a pass, because it does not appear to me that he was trying to be "hip" or "with it," and that his albums of cover versions were just caricatures or "send-ups," and never really meant to be taken seriously. If anyone has any evidence to the contrary, please feel free to post it.
