The British duo, properly known as Michael Flanders & Donald Swann, was composed of the actor and singer Michael Flanders and the composer, pianist and linguist Donald Swann, who collaborated in writing and performing comic songs. Flanders and Swann's songs are characterised by wit, gentle satire, complex rhyming schemes, and memorable choruses. They wrote over eighty comic songs together. Between 1956 and 1967 they performed some of their songs in their long-running two-man revues At the Drop of a Hat and At the Drop of Another Hat.
