As an Ikette, Arnold sang lead on the 1966 single "What'cha Gonna Do (When I Leave You)," backed by Brenda Holloway and Patrice Holloway for Phil Spector's Phi-Dan Records.
Arnold sang backing vocals on the Ike Turner produced side of the album River Deep – Mountain High.
She also appeared in the 1966 concert film, The Big T.N.T Show.
Arnold quit the Ike & Tina Turner Revue in the fall of 1966 after their tour with the Rolling Stones in the UK.
She remained in London to establish a solo career, with the encouragement of Mick Jagger.
Arnold noted the difference between how she had been treated in America and how she was received in England, saying, "A young black woman on her own in America in a white environment would not have been treated as well as I was in England."
Her friendship with Jagger helped her land a solo contract with Immediate Records, a label founded by Rolling Stones manager Andrew Loog Oldham.

Arnold enjoyed several major British hits on Immediate Records, including songs written for her by Paul Korda, who wrote "The Time Has Come".
She also recorded songs written by Steve Marriott and Ronnie Lane from labelmates Small Faces, who backed her on several recordings; Arnold had a brief romantic liaison with Marriott in 1967.
She toured with the Small Faces during 1967-68, made several TV appearances with them, and featured as backing vocalist on two of their biggest hits, "Itchycoo Park" and "Tin Soldier".
Other credits in this period include her duet with Rod Stewart on the single "Come Home Baby" (produced by Mick Jagger on Immediate Records, with Ron Wood on guitar, Keith Richards on bass, Nicky Hopkins on electric piano, Keith Emerson on Hammond organ and the Georgie Fame Brass Section), as well as Chris Farlowe's version of the Motown standard "Reach Out (I'll Be There)" (with Albert Lee on guitar and Carl Palmer on drums).

Her first backing band, the Blue Jays, had been inherited from American soul singer Ronnie Jones and included former Bluesbreakers guitarist Roger Dean.
This was followed by the Nice, whose line-up was Keith Emerson on organ, who had just quit the VIPs (later to be known as Spooky Tooth), David O'List on guitar, Lee Jackson on bass and Ian Hague on drums.
During this period she scored several hits, including the original version of Cat Stevens' song "The First Cut Is the Deepest" and "Angel of the Morning", plus the Marriott-Lane song "(If You Think You're) Groovy".

After the collapse of Immediate Records in the late 1960s, Arnold signed a production contract with the Robert Stigwood Organisation and released two singles on the Polydor label, produced by Barry Gibb, but a planned album with Gibb was never completed.
Between 1969 and 1970, she recorded eleven songs which were produced by Gibb himself but only two of the songs "Bury Me Down By the River" and "Give a Hand, Take a Hand" were released.
In February 1970, she sang harmony vocals on the song "Born" which was included on Gibb's debut solo album The Kid's No Good.
