1956: Jazz musician and bandleader Tommy Dorsey, who had a run of 286 Billboard chart hits from the 1930s into the 1950s, dies from choking in his sleep at the age of 51 in Greenwich, Conn. Dorsey's bands had 17 No. 1 hits including "On Treasure Island," "Indian Summer" and "Dolores." He also had two more No. 1 hits in 1935 with his brother Jimmy Dorsey as the Dorsey Brothers Orchestra, "Lullaby of Broadway" and "Chasing Shadows." His biggest hit was "I'll Never Smile Again," featuring Frank Sinatra on vocals, which was No. 1 for 12 weeks on the Billboard pop singles chart in 1940.
