The Castles may have had the “Castle Walk”, which was composed for them by band leader James Reese Europe, but Maurice Mouvet had the “Maurice Walk,” composed by Paul Biese and Henry Klickmann. The cover to the sheet music features Mr. Mouvet (who preferred to go simply by “Maurice”) and his partner/wife Florence Walton.
