By the mid-1950s Abbott’s health and habits had begun to erode the team’s onstage precision. In November 1956 Lou Costello was the subject of the popular TV program This Is Your Life, and the team returned to live performance the following month with a Las Vegas engagement that has gone down in comedy lore for all the wrong reasons. Contemporary accounts vary — some witnesses said Abbott’s timing had slowed so badly that Costello’s carefully timed responses were thrown off; another version has Costello leading a visibly inebriated Abbott offstage. Whatever the exact choreography, the performance was a public humiliation for a team that had once dominated box-office charts and radio ratings.
The episode crystallized long-simmering problems: Abbott’s drinking (which he later admitted was partly to control epileptic seizures) had degraded his reliability, Costello’s resentment over billing and money had hardened, and both men were coping with gambling and tax problems. The Las Vegas fiasco helped precipitate the team’s formal split in 1957. The tragedy was compounded when Costello died only two years later in 1959; Abbott, who would try briefly to team with others, often said no one could replace his old partner. The Las Vegas collapse remains a poignant coda to their partnership — an instance where the comedy that once seemed effortless publicly unspooled into a bitter and sorrowful unraveling.
