While Ellington's United States audience remained mainly African-American in this period, the orchestra had a significant following overseas. They travelled to England and Scotland in 1933, as well as France (three concerts at the Salle Pleyel in Paris) and the Netherlands before returning to New York. On June 12, 1933, the Duke Ellington Orchestra gave its British debut at the London Palladium; Ellington received an ovation when he walked on stage. They were one of 13 acts on the bill and were restricted to eight short numbers; the booking lasted until June 24. The British visit saw Ellington win praise from members of the serious music community, including composer Constant Lambert, which gave a boost to Ellington's interest in composing longer works.
