This film initially out-grossed "Buck Privates". Loew's Criterion in Manhattan was open until 5 a.m. to oblige over 49,000 customers during the film's first week. "Oh, Charlie" was put back into production to add music featuring the Andrews Sisters and Ted Lewis. The film was eventually released as "Hold That Ghost" (1941). The duo next made "Ride 'Em Cowboy" (1941), with Dick Foran, but its release was delayed so they could appear in a third service comedy, "Keep 'Em Flying" (1941). This was their last film with Arthur Lubin. All of their 1941 films were big hits, and Abbott and Costello were voted the third biggest box office attraction in the country in 1941. Universal loaned the team to Metro-Goldwyn-Mayer for a musical comedy, "Rio Rita" (1942). During filming Abbott and Costello had their hand and foot prints set in concrete at what was then "Grauman's Chinese Theatre". Back at Universal they made "Pardon My Sarong" (1942), a spoof of South Sea Island movies; and "Who Done It?" (1942), a comedy-mystery. In 1942 exhibitors voted them the top box office stars in the country, and their earnings for the fiscal year were $789,026. The team did a 35-day tour during the summer of 1942 to promote and sell War Bonds. The Treasury Department credited them with $85 million in sales. After the tour the team made "It Ain't Hay" (1943), from a story by Damon Runyon; and "Hit the Ice" (1943). Costello was stricken with rheumatic fever upon his return from a winter tour of army bases in March 1943 and was bedridden for approximately six months. On November 4, 1943, the same day that Costello returned to radio after a one-year layoff due to his illness, his infant son Lou Jr. (nicknamed "Butch" and born November 6, 1942) died in an accidental drowning in the family's swimming pool. Maxene Andrews remembers visiting Costello with sisters Patty and LaVerne during his illness, and remembered how Costello's 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. Once Costello recovered, they made "Lost in a Harem" (1944) at MGM, then returned to Universal for "In Society" (1944), "Here Come the Co-Eds" (1945) and "The Naughty Nineties" (1945).
