Bob Crosby is best remembered for the Dixieland band that bore his name during the 1930s and early 1940s. The Bob Crosby Orchestra, along with its combo side group, the Bob Cats, was considered one of the greatest jazz bands of all time. The orchestra was actually led by sax player Gil Rodin, however. Crosby himself was simply the front man, chosen for his personality, looks, and famous last name.
