When Louis Armstrong recorded Hello, Dolly in 1963, he became the oldest act to top the US charts when his recording reached number one in 1964 knocking the Beatles clear off the charts! Hello, Dolly, with lyrics and music by Jerry Herman and a book by Michael Stewart, was based on Thornton Wilderâs 1938 farce The Merchant of Yonkers. Wilder revised and retitled The Matchmaker in 1955.
