One of the greatest voices of the 20th century, as well as a mainstream television star hosting his own national show, this legendary jazz pianist turned world-class baritone recorded an "Unforgettable" catalog of classics. This 11-song collection includes that timeless track, later immortalized in a virtual duet with daughter Natalie Cole, and such standards as the No. 1 Billboard R&B hit, "Send for Me," "Mona Lisa" and Cole"s Yuletide perennial, "The Christmas Song."
