This is another jazz-flavored Betty Boop cartoon. This time, the band leader whose song is the title of this short is named Don Redman, a now-obscure artist. This short basically takes place in a mine where the workers go through a shower that washes the coal off their clothes before going to Betty Boop's Tavern (or Betty Boop's Saloon according to the cartoon backdrop display that appears in the live-action credits when Redman and his Orchestra plays) and then after we hear Don's rendition of a song that mentions the leading cartoon character's name Betty herself performs with a chorus of mice coming out of the stairs she's singing in front of. Lots of other bizarre stuff happens but, as always in a Fleischer cartoon, it's hard to describe. Well, actually after the miners go through the shower head again, the coal dirt comes back on! And as always, the music and animation matches perfectly. So on that note, I recommend I Heard.
