An energetic, chaotic musical comedy starring Peter Noone and his Herman's Hermits, the popular British pop group of the 1960s who had a top tune of the same name. Noone inherits a prize greyhound named Mrs. Brown and decides to make his fortune by racing the dog and eventually winning a national derby. The other Mrs. Brown, wealthy Washbourne, has a daughter, Caldwell. Noone and the boys eventually land a singing job in a nightclub, and both the dog and Caldwell disappear for a while. Later, the dog is found and wins a big race, plus gives birth to puppies. Noone gives up on Caldwell, but when she returns he notices that she has grown into a lovely woman. Producer Klein managed the Beatles for a while. All the songs are sung by Herman's Hermits and include "It's Nice to Be Out in the Morning," "Ooh, She's Done It Again," "Lemon and Lime," "The World Is for the Young," "Holiday Inn" (Graham Gouldman), "The Most Beautiful Thing in My Life" (Kenny Young), "Daisy Chain" (Peter Noone, Keith Hopwood, Karl Green, Derek Leckenby), "Mrs. Brown, You've Got a Lovely Daughter" (Trevor Peacock), and "There's a Kind of Hush" (Les Reed, Geoff Stephens).
