This is what we found on Wikipedia regarding the Herman's Hermits:

Herman's Hermits are an English rock and pop group formed in 1963 in Manchester and fronted by singer Peter Noone. Known for their jaunty beat sound and Noone's often tongue-in-cheek vocal style, the Hermits charted with numerous transatlantic hits in the UK and in America, where they ranked as one of the most successful acts in the Beatles-led British Invasion. Between March and August 1965 in the United States, the group logged twenty-four consecutive weeks in the Top Ten of Billboard's Hot 100 with five singles, including the two number ones "Mrs. Brown You've Got a Lovely Daughter" and "I'm Henry VIII, I Am".

Their other international hits in the 1960s include "I'm into Something Good" (their sole UK number one), "Can't You Hear My Heartbeat", the two covers "Silhouettes" and "Wonderful World", "A Must to Avoid", "Listen People", "No Milk Today", "There's a Kind of Hush", "I Can Take or Leave Your Loving", "Something's Happening" and "My Sentimental Friend", all of which were produced by Mickie Most. Herman's Hermits also appeared in four films, two of which were vehicles for the band.
