text_A: After ending his partnership with Martin in 1956, Lewis and his wife Patty took a vacation in Las Vegas to consider the direction of his career. He felt his life was in a crisis state: "I was unable to take steps forward in life with any level of confidence. I was completely unnerved to be alone". While there, he received an urgent request from his friend Sid Luft, who was Judy Garland's husband and manager, saying that she couldn't perform that night in Las Vegas because of strep throat, and asking Lewis to fill in.
text_B: If Lewis were to answer Sid Luft's call, and work as a substitute for Judy Garland in Las Vegas, does it sound like he would try to rehash his familiar routines on stage?
YES.
