Think of the album Foreverly as a musical equation. You start with Billie Joe Armstrong, lead singer of Green Day . Then you add Norah Jones.

"I'm a big vinyl collector, so I was just flipping through the bins," Armstrong says of discovering Songs Our Daddy Taught Us, a lesser-known album of traditional tunes recorded by The Everly Brothers. "I thought it would be cool to remake the record. But I thought it would be cool to do it with a woman."
Norah Jones was game for the challenge, if a little unsure how their voices would sound together — especially, she says, attempting the close two-part harmonies that are the Everlys' trademark. Once she and Armstrong got to the studio, one rule made all the difference.
