He's a pioneer. In 1973, Robert Klein released his first album, "Child of the Fifties," which brought Klein to a vast audience and won him a Grammy Award nomination. That same year, Klein sold out Carnegie Hall with "The First Annual Robert Klein Reunion." For nearly two hours, Klein knocked out his audiences with his high energy commentary. The critics raved, and Klein affirmed his place as a major personality in contemporary entertainment and as an influence on a whole generation of comedians. In 1979, Klein returned to Broadway with a Tony nomination for Best Actor, and a Los Angeles Drama Critics Circle Award for his performance in the hit musical, "They're Playing Our Song.” Robert has been a regular guest on "The Tonight Show" and has guest-hosted the show on numerous occasions. He  has also appeared regularly on “Late Show with David Letterman" and "Late Night with Conan O'Brien." Klein also hosted "Saturday Night Live" twice. Klein's movie roles include: "Hooper,""'The Owl and the Pussycat," "Radioland Murders," "Mixed Nuts," "One Fine Day,' "Next Stop Wonderland," "Primary Colors," "Goosed," and "People I Know" with Al Pacino. In 1975, Klein was the first comedian to appear in a live concert on the precedent setting HBO "On Location" series, and has done seven one-man shows since for HBO. His 1982 show, "Robert Klein at Yale," has been added to the permanent collection of The Museum of Broadcasting. More recent credits include "The King of Queens," "The Mysteries of Laura" and "Madam Secretary." Robert Klein has influenced generations of comics, and he's a legend that must be seen.
