"Warleigh Manor" is an album by Holdsworth/Warleigh/Mathewson/Spring, released in 2020. The album features what sounds like a rehearsal tape from the 70s with Allan on guitar, Allan's mentor Ray Warleigh on flute, Ron Mathewson on double bass, and Bryan Spring on drums. The recording stems from private tapes that have recently been unearthed in the archives of Ron Mathewson. The album therefore carries the subtitle "The Ron Mathewson Tapes Vol. 1".
