A fragment of music attributed to Croft, Ground in C minor (D221), has been used by contemporary composer Michael Nyman as the source of his piece An Eye for an Optical Theory.

[7] Bach's Fugue in E-flat major, BWV 552, is often called the "St. Anne", due to the similarity (coincidental in this case) of its subject to the hymn melody's first phrase.
