During a tour of North America's west coast the relationship between Farren and the musicians became personally and musically strained, and the band decided to continue without Farren, who returned to England, where he teamed up with ex-Pretty Things drummer Twink (born John Charles Alder, 29 November 1944, in Colchester, Essex) and Steve Peregrin Took (born Stephen Ross Porter, 28 July 1949, in Eltham, South East London) to record the album Mona – The Carnivorous Circus, an album interspersed with interviews with Took and a member of the U.K Hells Angels before concentrating on music journalism.

The three remaining musicians - Rudolph, Sanderson and Hunter - continued in North America for some months occasionally playing gigs there under the Deviants name, before returning to England early in 1970, and teaming up with Twink to form the Pink Fairies.

This band, without Rudolph, went on to record the album Vampires Stole My Lunch Money and the non-album single "Broken Statue", both credited to Mick Farren rather than The Deviants.

He would resurrect The Deviants name for occasional live performances, such as in February 1984 when he teamed up with Wayne Kramer and Wallis' band which featured Sanderson and drummer George Butler.

In 2002, a new line-up of the band (featuring bassist Doug Lunn, drummer Ric Parnell and vocalist Michael Simmons) released Dr. Crow.

Farren then continued to perform and record sporadically under the name The Deviants, using a pool of musicians which include Andy Colquhoun and former Blodwyn Pig saxophonist Jack Lancaster.
