There's Honey Baby by Three Plus, Drop Baby Drop by Ka'au Crater Boys, and Wonderful Tonight Cover and Stuck on You Cover by Ekolu. These are pretty simple songs but I suggest you go with Nuke and learn a song you like. It makes things easier cuz your more familiar with the song which makes things so much easier.
And to add to that, you can't forget Molokai Slide. That was a great starting song for me.
