Besides "A Whiter Shade of Pale", "Conquistador" was the band's highest charting single. It peaked at #16 on the "Billboard" Hot 100 on 29 July 1972, exactly five years to the date after "A Whiter Shade of Pale" ascended to its #5 peak, and helped catapult the album into the top five. "Conquistador" peaked at #22 on the UK Singles Chart. The song was generally well received by music critics. Bruce Eder of Allmusic praised it as "the most accessible song" on "Procol Harum Live In Concert with the Edmonton Symphony Orchestra", adding that "nothing else [on the album] matches it for sheer, bracing excitement." It was listed on Dave Thompson's "1000 Songs that Rock Your World".
