Boy, What a Night was composed by Lee Morgan and recorded on December 21, 1963, at Rudy Van Gelder Studio in Englewood Cliffs, New Jersey, for Blue Note Records as part of the album The Sidewinder. The quintet featured Morgan on trumpet with Joe Henderson on tenor saxophone, Barry Harris on piano, Bob Cranshaw on bass, and Billy Higgins on drums. The composition is a hard bop piece distinguished by its driving 6/8 feel, which gives it a pile-driving momentum and a flavor reminiscent of Charles Mingus's rhythmic approach. This metric choice sets it apart from the other tracks on the album, which lean toward boogaloo and Latin-inflected swing grooves. The energetic melody supports extended improvisation across the tune's seven-and-a-half-minute runtime, with the ensemble maintaining a crackling intensity throughout. Morgan wrote all five compositions on The Sidewinder at age 25, and Boy, What a Night exemplifies his blues-based, R&B-inflected hard bop writing during a period that marked his triumphant return to recording after personal difficulties. The album itself became a commercial breakthrough for Blue Note, reaching number 25 on the Billboard charts and later being added to the U.S. National Recording Registry. While the title track achieved jazz standard status, Boy, What a Night remains a deep cut appreciated primarily by listeners who explore the full album. The original session is featured on AllSolos with transcribed solos from Henderson, Morgan, and Harris.
