Guy Lombardo
On November 5, 1977, Lombardo suffered a fatal heart attack. Another source says he died "of a lung ailment." His wife was at his bedside when he died in Houston Methodist Hospital.
Lou Costello
In March 1943, after completing a winter tour of army bases, Costello had an attack of rheumatic fever and was unable to work for six months. On November 4 of that year, he returned to the team's popular radio show, but upon arriving at the NBC studio, Costello received word that his infant son, Lou Jr., had accidentally drowned in the family pool. During an afternoon nap, the baby worked loose one of the slats on his crib, climbed out and fell into the pool, unnoticed by the nanny. The baby ('Little Butch') was just two days short of his first birthday. Lou had asked his wife to keep Butch up that night so the boy could hear his father on the radio for the first time. Rather than cancel the broadcast, Lou said, "Wherever he is tonight, I want him to hear me", and went on with the show. No one in the audience knew of the death until after the show when Bud Abbott explained the events of the day, and how the phrase "The show must go on" had been epitomized by Lou that night. Costello's close friend, Maxene Andrews of The Andrews Sisters, said that his entire demeanor changed after the tragic loss of his son, saying, "He didn't seem as fun-loving and as warm ... He seemed to anger easily ... there was a difference in his attitude."
