After having found success with The Foundations, two hit singles and releasing two albums, some problems started with their songwriter producer Tony Macaulay as well within the group. Curtis felt that after their hit a couple of The Foundations members were taking things a little too easy thinking that they did not need to work so hard now that they had scored a hit. After being disillusioned with the band, he along with another member, Mike Elliott, left The Foundations in 1968 just after recording a version of "It's All Right", a song that they had been playing live for some time. He stuck around long enough to help the band audition a replacement, Colin Young. Curtis went on to pursue a solo career in the United States. This was probably helped along by the encouragement of his friend Sammy Davis Jr.
