English rockers Procol Harum recorded "Conquistador" on August 6, 1972 during a live performance with the Edmonton Symphony Orchestra. The single reached #16 on the Billboard chart that same year becoming just their third, and final, Top 40 hit. The band was named for a friend's cat. Procol Harum was nominated for the Rock And Roll Hall Of Fame in 2012, but failed to muster enough ballots for induction.
