Though I DO wish folks would at least appear to do the simple internet search for such things before they clutter up discussion forums, there is a compelling reason for such requests in the Mudpond. The collective knowledge here is immense. If one asks for a song they're likely to get a variety of obscure versions as well as the current pop darling's version, versions in different styles, from different geographic influences and cultures, and so on, all of which might involve variations on the chords, progressions, melody, and lyrics.
Not everyone can pull chords out of the air with only the melody to work with, and even fewer can pull the correct (by a recorded standard) chords from the air. Fewer still can create an interesting variation with alternate chords. That they ask here is smart because they should get usable answers with intelligent discussion.
