Hi,
I am not sure that any song of his stands out for me.
In this case, I think his attitude and playfulness with his music, is much more important and gives the venue of rock'n'roll a personality that is much more important and valuable to the music itself.
I think his playfulness is what helped extend this to the rest of the world ... I do not think it was just one song, or one set of lyrics, or one girl ...
