Natalie Cole's "Unforgettable" Follow-Up

Sept. 9 release date announced for Still Unforgettable which will feature another digital duet with Natalie's late dad, Nat King Cole

Natalie Cole is doing her best to make sure her dad's velvety voice lives on.

The soulful songstress has announced plans for Still Unforgettable, a follow-up to her Grammy-winning 1991 cover album Unforgettable: With Love, which featured the singer's infamous digital duet with her father Nat King Cole on the crooner's classic 1951 ballad "Unforgettable."

It's technology that has allowed the pair to share the spotlight, considering Cole's pop died in 1965, when she was only 15.

Still Unforgettable, due out Sept. 9, will feature a host of pop standards and another father-daughter duet, this time on "Walkin' My Baby Back Home," which Nat recorded in 1952.

"You never get over missing your dad as the years go by, particularly around Father's Day," Cole said in a statement, and it's the fans who sent her back to his catalogue "looking for more treasures—and I was not disappointed."
