Ivor Moreton and Dave Kaye were an English musical variety double act who were known for performing syncopated piano duets together from the 1930s to 1950s. The duo consisted of pianists Ivor Arthur Moreton (born Arthur Lethbridge; 18 March 1908 – 9 December 1984) and David "Dave" Kaye (born David Keigel; 13 March 1906 – 15 December 1996), who had both been members of Harry Roy's dance band, the act developing from Roy's small group, the Tiger Ragamuffins. They played at two pianos, usually with Kaye carrying the melody, and Moreton embellishing it.
