This is one of the newest of the Vitaphone shorts--known as a "Melody Master". These later musical shorts generally had been more straight forward and had simpler sets and no real story to tie it all together--just a famous band of the day doing their stuff. However, starting during the war years these shorts began to have a narrator and purported to give a bit of background on the band leader.
"Six Hits and a Miss" is very unusual for a Melody Master in that the film is not named after a band leader and he and his band are really NOT the stars of this short. The title refers to a rather dull septet--with five neat guys singing along with a lady. The film also features the Dancing Colleens. I must admit that this routine was pretty spectacular--like one from an old Busby Berkeley musical. However, when the couple dance, the tapping sound appears to have been provided by the band--not their shoes. Finally, you see Rudolf Friml Jr. and his band. Overall, one of the duller entries into the series and why they named the short after this group, I have no idea.
