After smoking three packs of cigarettes a day for many years, Nat King Cole died of lung cancer at the age of 47. His daughter Natalie had just turned 15 the previous week. Nat originally played piano in Jazz bands, but stepped to the front of the stage for good when "Mona Lisa" became a number one hit in 1950. Cole continued his hit streak with "Unforgettable" (#12 in 1951), "A Blossom Fell" (#2 in 1955), "Send For Me" (#6 in 1957), "Looking Back" (#5 in 1958), "Ramblin' Rose" (#2 in 1962) and "Those Lazy-Hazy-Crazy Days of Summer" (#6 in 1963). He hit the charts again in 1991 when his voice was dubbed into a duet with Natalie on an updated version of "Unforgettable", which rose to #14.
