In 1972, Patrick co-founded the Baritone Saxophone Retinue, which recorded two albums for Saturn Records. He toured Europe with Ra in 1970 and 1976, and was part of some other Arkestra performances in that decade, but he also devoted time to teaching at the State University of New York at Old Westbury. He was a frequent member of the Arkestra again from 1986 to 1988. "Grove Music" wrote that, "Patrick was a well-schooled, versatile soloist and ensemble player and made an important contribution to Sun Ra's music. Besides his principal instrument, which was baritone saxophone, he played flutes, bass, and percussion." He died from leukemia in Moline, Illinois, on December 31, 1991.
