Google paid tribute to Israel Kamakawiwo'ole on Wednesday (April 20) to celebrate Asian Pacific American Heritage Month on what would've been the singer's 61st birthday.The colorful animated Doodle finds the late Hawaiian music great -- who passed away in 1997 at the age of 38 -- performing his iconic rendition of "Somewhere Over the Rainbow," strumming his ukulele as he sits peacefully on the beach and picks plumerias.
