Speaking in July 2008 to noted UK soul writer Pete Lewis of the award-winning Blues & Soul, Cole discussed the thinking behind 'Still Unforgettable': "While we were still trying to create that same 'Unforgettable'-type mood or environment, this time I wanted to expand. Rather than just doing another Nat 'King' Cole tribute - which was not necessary - I wanted to go deeper into the American Songbook, by not just getting songs from my father, but also from other singers of his time like Frank Sinatra, Lena Horne, Sammy Davis Jr. and Peggy Lee. You know, there was something about the approach that the writers from that era had to the lyrics and the melodies that was so intentional, so purposeful. Which I think is the thing that's missing from music today."[4]
