 After returning to civilian life in 1919, Fancourt sang in a single performance of "Prince Igor" in Sir Thomas Beecham's opera season at Covent Garden as Prince Galitsky under the baton of Albert Coates.This was his only professional appearance in a grand opera, and his only paid acting experience up to that point.In the same year, he appeared as a soloist at the Henry Wood Promenade Concerts and in oratorio elsewhere in London.
