American jazz trumpeter, singer and bandleader, Louis Armstrong died on July 6th 1971. Had many hits including the 1964 US No.1 ‘Hello Dolly!’, 1968 UK No.1 ‘What A Wonderful World’ plus ‘When The Saints Go Marching In’, ‘Ain’t Misbehavin’, and ‘We Have All the Time in the World.’ He made frequent use of laxatives as a means of controlling his weight, resulting in Armstrong appearing in humorous, advertisements for laxative product Swiss Kriss; the ads bore a picture of him sitting on a toilet, as viewed through a keyhole, with the slogan “Satch says, ‘Leave it all behind ya!”
