 "Bob Crosby, Bing's younger brother, often found himself in the odd position "
 'of being the least important member of his own orchestra. An okay singer, '
 'Crosby was much more important as the leader of a memorable swing band that '
 "found its own style by looking backwards to the 1920s. To Crosby's credit, "
 'he seemed aware of his predicament and not uncomfortable at allocating most '
 'of the solo space to his talented sidemen, featuring them with his big band '
 'and his Bobcats, the latter a hot Dixieland band taken out of his orchestra. '
 "After stints with Anson Weeks in 1932 and the Dorsey Brothers' orchestra "
 'during 1934-1935, Crosby was voted the frontman of a new big band that was '
 "formed out of the remains of Ben Pollack's orchestra. The 1935-1942 period "
 "was Crosby's heyday, with his band featuring such classic soloists as Yank "
 'Lawson, Billy Butterfield, Eddie Miller, Matty Matlock, Irving Fazola, Joe '
 'Sullivan, Bob Zurke, Jess Stacy, and Muggsy Spanier. During an era when '
 'swing was the thing and New Orleans jazz was considered by many to be '
 "ancient history, Crosby's crew led the way to the eventual New Orleans "
 'revival. Such classic recordings as "South Rampart Street Parade" and '
 '"What\'s New" (both composed by bassist Bob Haggart) along with the many '
 'Dixieland stomps kept the band quite popular. The orchestra broke up in late '
 '1942, Crosby served in the Marines during 1944-1945, and then spent the rest '
 'of his life in a variety of activities, often bringing back versions of the '
 'Bobcats for special concerts and recordings, taking an occasional vocal but '
 "mostly letting his sidemen play. Some of Crosby's many Decca recordings are "
 'currently available. \r\n'
