The arseh*le "guest who started this thread askes why does somebody need the chords if they know the tune - is he or she thick? Usually people ask for the chords so that they can PLAY to accompany the tune. Also what does "knowing the tune" mean? Knowing how it sounds, being able to hum it? Do you assume that everyone that asks for chords is an acomplished musician? It's not always G, C & D. There are sometimes a lot of sublties invoved. This is why there is a huge market in published books of chords for various songs.
