Song In 50 First Dates

I was just wanting to find out if anyone new what the name and artist of the song that is played right after Lucy and Henry say goodbye for the first time at their cars. Then they start dancing and this song is played. It has a hawaiin vibe.

Also I have noticed that different parts of the song play through out the movie. It like the main score of the movie. But it isn't in the actual movie soundtrack

Thanks for the help.
