Fats Waller being, well, Fats Waller, with vocalist Ada Brown, from the 1943 film Stormy Weather:

Later in the same film, Ain't Misbehavin' - with Lena Horne looking glamorous.

It's all a bit hokey – black folks having a fine old time – but the film was selected in 2001 for the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant." So there you go.

Fats died in December of that year, aged 39. 

An eventful life:

Waller was kidnapped in Chicago leaving a performance in 1926. Four men bundled him into a car and took him to the Hawthorne Inn, owned by Al Capone. Waller was ordered inside the building, and found a party in full swing. Gun to his back, he was pushed towards a piano, and told to play. A terrified Waller realized he was the "surprise guest" at Capone's birthday party, and took comfort that the gangsters did not intend to kill him. It is rumored that Waller stayed at the Hawthorne Inn for three days and left very drunk, extremely tired, and had earned thousands of dollars in cash from Capone and other party-goers as tips.
