Do a Google search with the word "Chords" followed by the tile of the song you want. This will usually produce several results. You can also use the word "Tabs" for your search. If you wish to sing the song in a different key use the URL above to transpose it to your required key. Just one word of caution - sometimes you will find songs submittied by "three chord merchants" who mean well but will not be accurate .
