Their name 'Mojo Men' was put onto their recording by their label (Tide (2)) unbeknownst to them in an effort to cash in on the Mojo craze at that time.
Tom left the band in the summer of 1965 along with some other personnel changes. The band was eventually signed with Mike Curb in 1966.
At that time they had to change their name again becoming The Portraits and recorded for Tide (2).
They also recorded as 'Paul & The Pack for a one shot soundtrack recording.
