By the early 1930s, Harry Roy was fronting the band under his own name, and broadcasting from the Café Anglais and the Mayfair Hotel. In 1931 he wrote along with Anthony Fanzo and sang "My Girl's Pussy", which has since been the subject of many cover versions and remakes.
In 1935 he married Elizabeth Brooke, daughter of the white Rajah of Sarawak, with whom he appeared in two musical films, Rhythm Racketeer (1937) and Everything Is Rhythm (1940).
During the Second World War, Roy toured with his band, Harry Roy's Tiger Ragamuffins. He was at the Embassy Club in 1942, and a little later, toured the Middle East, entertaining troops.
