How did this song come about? Group member Dan Ponce credits an ex-girlfriend with the unique combo. "When I was playing the chords to 'I'm Yours,' she said, 'That sounds like 'Somewhere Over the Rainbow,' " he says. "I started laughing and said, 'Wouldn't it be cool to combine those two songs?'

And so they did. Check it out here!
