The name Led Zeppelin was inspired by a sarcastic comment from Keith Moon, the drummer of The Who. In 1966, Moon and Who bassist John Entwistle played on a recording session with Jimmy Page. They joked about forming a supergroup, but Moon remarked that the idea would go down like a 'lead zeppelin'—a play on the phrase 'lead balloon.' When Page eventually formed his own band in 1968, he remembered the joke. He changed the spelling of 'Lead' to 'Led' at the suggestion of manager Peter Grant, to prevent fans from mispronouncing it as 'leed.' The name perfectly suited their sound: heavy and metallic (Led) but capable of soaring, airy dynamics (Zeppelin). They became one of the most successful and influential rock bands in history, with 'Led Zeppelin IV' becoming a multi-platinum cornerstone of the genre.
