Rhythm guitarist/singer Mike Millward (ex-the Undertakers) joined the Four Jays in November 1961, followed by drummer/singer Dave Lovelady in September 1962.

[5] This led to their being auditioned by George Martin and signed to EMI's Parlophone record label.

It was also notable as one of the earliest Beatles-penned songs to be released in the United States but, as with the Fourmost's other singles, it failed to chart there.

[12] Other tracks included "My Block" sung by Hatton[11] and written by Jimmy Radcliffe, Carl Spencer and Bert Berns (originally a hit for the Chiffons in 1963), Millward sang a re-make of "The In Crowd",[12] which featured the brass section from Sounds Incorporated, and Hatton sang cover versions of Little Richard's "The Girl Can't Help It" and "Heebie-Jeebies".

In early 1966, the band was rocked by the sudden death of rhythm guitarist/vocalist Mike Millward from leukaemia.

Peckham wrote and sang the country-influenced "Turn the Lights Down Low" (the B-side of "Auntie Maggie's Remedy"), a short-lived effort to branch out to less pop-oriented fare.

A later private pressing album, The Fourmost – featuring O'Hara, Hatton, Lovelady and Bower – included covers such as "Without You", "I've Got You Under My Skin", "Rag Doll" and "Save the Last Dance for Me"; it was sold at their shows in 1975.

[15] In 2005, they also released a 33-track CD compilation The Best of The Fourmost, which included the stereo version of "I Love You Too", and four previously unreleased songs with booklet notes written by Hatton.

[16] In 2008, Hatton and Lovelady lost a court case to own the trademark on "The Fourmost" name, to the iteration of the band dating back to when they both left in 1978.
