FZ asked Jobson to accompany the Mothers Of Invention the following month for a week in Canada. Eddie guested on violin in Hamilton, and Montreal - all the while playing with FZ in dressing rooms and hotels as Frank assessed his talents - and became a member of the band in 1976. Jobson appeared on the cover of Zoot Allures though he didn't play a note on it. He did however perform on Zappa In New York.
