Synopsis by Hal Erickson
On furlough from WW2, Popeye hopes to get some rest and relaxation at home, but his four nephews insist upon keeping him awake with a musical concert. Finally managing to bundle his nephews off to bed, Popeye settles down for a good night's sleep. Meanwhile, the four bored nephews discover that various items in their bedroom can be converted into musical instruments--and the result is a loud, swinging midnight jam session, much to Uncle Popeye's dismay. This exquisitely timed and paced black-and-white "Popeye" cartoon was later remade in color, scene for scene, as Riot in Rhythm (1950).
