Classic Duets is a 2002 compilation album by Frank Sinatra. Given his enormous talent and unparalleled musical history—not to mention the healthy, suffer-no-fools ego they inspired—it is hardly surprising that duets are relatively few and far between in Frank Sinatra's catalog, his smash duet on "Somethin' Stupid" with daughter Nancy notwithstanding. But in the heyday of the TV variety show, the star-hosted format virtually demanded musical cross-pollination, a tradition that carried over from radio. It's that fertile, largely unexplored territory that this rewarding, 21-track anthology explores in conjunction with the PBS special of the same name.
