Clearly I my musical tastes haven't changed much, because I'm fairly certain that in at least one previous iteration of this list, I chose this musical theater gem:
Various Artists -
Candide [Original Broadway Cast - 1956] (1957)
Barbara Cook's performance as Cunegonde is quintessentially glittery and gay, and her voice pairs well with Robert Rounseville, who sings the title role. The original libretto by Lillian Hellman (with contributions from Dorothy Parker, John Latouche, and Richard Wilbur) is wonderfully witty, and Bernstein offers up some of his most effective music to complement it.
