Paddy, sorry, I don't know the chords, though I think they're actually a simplified version of the original, but if you want to find out more about Iz and his music, check out this Israel Kamakawiwo'ole Tribute Page. I believe the song was also used in the movie "Meet Joe Black", and the ukulele instrumental break was in a TV commercial, for Wal-Mart, I think. He was a magnificent singer, and is sorely missed by people here in Hawaii and around the world.

Aloha,
Mark
