Andrew Pryce Jackman (1946 – 16 August 2003) was a keyboard player and arranger. He was in The Syn with bassist Chris Squire (later of Yes). Jackman subsequently worked on Squire's solo album Fish Out of Water (1975), his single "Run with the Fox" (1980), on the Yes album Tormato (1978) and on The Steve Howe Album (1979).
In the mid-1960s, Jackman was the keyboard player in The Selfs with Squire and drummer Martyn Adelman. The Selfs then amalgamated with another Kingsbury (North West London) band, The Syn, led by Steve Nardelli. Nardelli and Jackman became the main songwriters for The Syn.
Following the demise of The Syn, Nardelli and Jackman continued to work together for a period. Jackman went on to concentrate on doing orchestral and other arrangements for various bands, including Peter Skellern, The Congregation, Rush (Power Windows) and Barclay James Harvest (string arrangement for "Guitar Blues").
He hooked up again with Squire, providing arrangements and pianos on his Fish Out of Water (1975) album and then working with Yes, providing an orchestral arrangement for the Squire-penned "Onward" on Tormato (1978). He also worked with Yes guitarist Steve Howe on several occasions.
His brother Gregg Jackman is a sound engineer and producer who has worked with Yes, Enya and Barclay James Harvest. His brother Jeremy Jackman sang countertenor with the King's Singers for ten years. Their father, Bill Jackman, played clarinet on "When I'm Sixty-Four" on The Beatles' Sgt. Pepper's Lonely Hearts Club Band.
