Abbott and Costello's first time as hosts. Several comedy routines including their classic: "Who's On First". Martin & Lewis were still in Hollywood making That's My Boy, so Abbott & Costello filled in. This episode, not only A&C's first for The Comedy Hour but their first TV appearance ever, includes the team's famous "hot dog and mustard" routine. Gould of The Times observed, "As is not unusual with television debuts, both Mr. Costello and Mr. Abbott seemed a little ill at ease on stage and far from relaxed," and noted, "their medium was much newer than their material." Despite Gould's reservations, the boys are in fine form, and the audience roars with laughter.
