Twenty-eight performers died in the course of their tours, from plane crashes, illness, or diseases contracted while on tour. In one such instance in 1943, a plane carrying a USO troupe crashed outside Lisbon, killing singer and actress Tamara Drasin, and severely injuring Broadway singer Jane Froman. Froman returned to Europe on crutches in 1945 to again entertain the troops. She later married the co-pilot who saved her life in that crash, and her story was made into the 1952 film "With a Song in My Heart", with Froman providing the actual singing voice. Others, such as Al Jolson, the first entertainer to go overseas in World War II, contracted malaria, resulting in the loss of his lung, cutting short his tour.
