A recording of one of the final performances by jazzman Louis Armstrong is now available to the public for the first time.
It was made at the National Press Club in Washington DC in 1971, five months before he died.
Armstrong had heart and kidney trouble, but felt strong enough to play five songs at the event.
His performance has been released as a digital download and on CD. It includes classics such as Hello Dolly, Mack the Knife and Rocking Chair.
