I’m a big fan of Fleischer Studios cartoons and of Mills Brothers music… here are the two together.
The Mills Brothers were somewhat of a novelty act, since the only instrument they used in the 30’s was a guitar… the rest of the “instruments” were produced by their voices. The music would be just as enjoyable without knowing this, though.
If you dig the music of the Mills Brothers, check out this well-made and inexpensive collection of their best recordings from JSP Records. You may wanna check out the rest of the stuff in the JSP Records catalog too… as well as Proper Records. Those two publishers are putting an amazing quantity of wonderful old music into well-researched, inexpensive cd box set collections.
