Announced as "The Atom Heart Mother" by the British broadcaster John Peel on his BBC Radio 1 show "Peel's Sunday Concert" on 16 July 1970, a name suggested by him to the band, it was also announced as "The Atomic Heart Mother" two days later at the Hyde Park free concert. Partly because of the difficulties of finding and hiring local orchestras and choirs, the band often played what is referred to as the "small band" version of the song when they performed it live.
