Wayne Fontana founded the band with Bob Lang, Ric Rothwell, and Eric Stewart in 1963. They released a few unsuccessful singles before recording "Um Um Um Um Um Um" in 1964, which was a major hit in Britain and led to a tour with Brenda Lee. They also had a number one hit in the United States with "The Game of Love."
After a tour of America and some more unsuccessful singles, Fontana abruptly left the band in the middle of a concert in 1965. Guitarist Eric Stewart suddenly became the lead singer of the band, which immediately dropped "Wayne Fontana" from its name.
