"IT JUMPS! IT JIVES! It rocks with red hot rhythm!"
1942's Private Buckaroo is a lavish musical enlistment brochure. Featuring Harry James (and His Orchestra), The Andrews Sisters, Dick Foran, Joe E. Lewis, Donald O'Connor, The Jivin' Jacks and Jills, Peggy Ryan, Shemp Howard, Huntz Hall, and Helen Forrest.
The plot (what there is of it) is simple: Harry James is drafted, as is his lead singer Lon Prentice (Foran). Foran is not hot on the idea of regulations and training -- certainly not for someone as famous as he. There's singing. And there's Shemp Howard doing his best work as a sole performer.as Muggsy Shavel.
If that's not enough, there are characters with names like Lancelot Pringle McBiff, Bonnie-Belle Schlopkiss, Corporal Anemic, and Nightclub Patron Awaiting Table. (Well, blink and you'll miss that last one.)
Private Buckaroo was directed by former Keystone Kop Edward F. Kline ( The Bank Dick, Private Snuffy Smith, Ghost Catchers) and written by Edmund Kelso (The Oregon Trail, King of the Zombies, Freckles Comes Home) and Edward James (Over My Dead Body, The Adventures of a Rookie, Rookies in Burma) from a story by Paul Girard Smith (Harold Teen, Topper Returns, You're in the Army Now).
