Greatest Cover Songs Ever

I realize this is a very tired topic, but I’m a big hater of cover songs of virtually any kind, and I was just talking about them in relation to the Beach Boys’ “Surfin’ USA,”  so I just thought I’d put it out there to see if anyone wanted to note one or two great cover versions they know (I know, it's a tired--but true--topic).  I’m thinking of a couple now, but I don’t know if I can call them great.  They really, really, people, have to be *great*.  No joke great is what they have to be.  The greatest of the greatest by the people who didn’t even. . . .
