"Mrs Brown, You've Got a Lovely Daughter" is a popular song written by Trevor Peacock. It was originally sung by actor Sir Tom Courtenay in The Lads, a British TV play of 1963. The best-known version of the song is by Herman's Hermits, who took it to number one on the U.S. Billboard Hot 100 in April 1965. Herman's Hermits had two U.S. number-ones, the other being "I'm Henry VIII, I Am". The band never released them as singles in Britain. "Mrs Brown, You've Got a Lovely Daughter" was recorded as an afterthought in two takes and featured unique muted rhythm guitar by Keith Hopwood and heavily accented vocals by Peter Noone with backing from Karl Green and Keith Hopwood. The band never dreamed it would be a single let alone hit number one in the U.S. According to Pete Noone, the song was well known to British bands; it would often be performed at birthday parties, substituting the name of the girl whose party was being celebrated, i.e. "Mrs. Smith" or "Mrs. Jones" instead of "Mrs. Brown".
