I just discovered this rare musical short from M-G-M on the TCM site. It's directed by comedian Buster Keaton at a low point in his life when the studio he worked for had no use for his physical talents. The stars are the musical group The Original Sing Band, a group of African-Americans who don't play instruments but instead use their mouths to sound like them while others sing the lyrics of which two of the performed songs were written by Louisiana native Leon Rene. Actually, one of them does play the guitar. The flimsy plot has them getting "sold" a railroad car by a "millionaire" who plans to retire on his "yacht". They take it off the tracks and turn it into a diner called "Dinah" (get the play on words?). While there's some embarrassing dialect here, this was mostly entertaining stuff courtesy of the singing. Since the Original Sing Band appeared in one other short, this was a real find for me. I highly recommend Streamlined Swing.
