"John Adams, the composer of this easily played collection, was a pupil of C. S. Lang of Tuba Tune fame. His preludes, mostly just two pages, bear all the hallmarks of an organist who writes with affection for and understanding of his instruments."
I know nothing else about this composer/organist!
This short one page prelude on the hymn tune 'Love Divine' for manuals comes from 'Ten Preludes for Organ' published by Kevin Mayhew.
