Hey Doll Baby is a newly remastered 17-track compilation that collects some of the lesser-known, buried treasures in the Everly Brothers' rich catalog with songs assembled by Adria Petty, Tom Petty's daughter, who worked closely with both Everly families on the project, with help from Phil's widow Patti and son Jason, who provided track-by-track commentary for the liner notes, as well as Don Everly, prior to his passing, and his widow Adela. Hey Doll Baby holds the bittersweet distinction of being the final project Don worked on.
