A powerful 1960s antiwar song from an unlikely source. Michael Flanders and Donald Swann were best known for their witty, urbane and sometimes sharply ironic songs commenting on modern life. 'At the Drop of a Hat' was their first hugely successful review on the London stage. This song was considered, by theatrical producers, to be too much out of character for live performance and survives only as a studio recording. For clarification, the rather considerable explosive power of one ton of the conventional chemical explosive trinitrotoluene (TNT) is used as a unit of this power.
