In 1967, frustrated by their continuing lack of success, the Zombies signed a recording contract with CBS Records for whom they recorded the album "Odessey and Oracle" at EMI's world-famous Abbey Road studios. ("Odyssey" was accidentally misspelled by Terry Quirk, an art teacher who designed the cover). The band's budget did not stretch to session musicians, so they used a Mellotron to fill out their arrangements. According to Argent, they used John Lennon's Mellotron, which had been left in the studio after the Beatles' sessions for "Sgt. Pepper's Lonely Hearts Club Band". The album was mixed into the standard mono; however as another concession toward their limited budget, Argent and White (who, due to their songwriting royalties, had earned more than the rest of the members) personally paid for stereo mixes.
