After returning to England in '64, they again worked as a backup band for a legendary American star, this time Bo Diddley.

Under the management of Don Arden and the guidance of producer Mickie Most, they made their first record in '64, a cover of John D. Loudermilk's "Tobacco Road". The follow-up, another Loudermilk composition, "Google Eye", also made the top ten, but after that the band made little impact. The blame for this mainly lies with their record company, Decca, who did little to promote them and often gave them material which was unsuitable to their style. They were also frustrated in their attempts to break into the American market when visa restrictions curtailed a US tour with The Zombies.

In 1965 the Teens appeared in the film "Pop Gear" alongside the Animals.

In the late Sixties they reverted back to working for American artists touring Britain, backing up Carl Perkins and Chuck Berry. Jenkins left to join the Animals in '66 and was replaced by one of his predecessors, Roger Groom. Hawken later played with ex-Yardbird Keith Relf in Renaissance.
