West End and Broadway
In the early 1920s Blore toured in variety and appeared in the West End in Angel Face (1922), a "musical farce" with music by Victor Herbert, heading a cast that included Sylvia Cecil and the young Miles Malleson, and The Cabaret Girl, joining the cast in mid-run.
In August 1923 Blore appeared for the first time on Broadway, playing the Hon. Bertie Bird in Little Miss Bluebeard, and on his return to London he appeared in the same part at Wyndham's Theatre. After the death of his first wife, Violet (née Winter), Blore married Clara Macklin in 1926. In the same year he returned to New York, playing Teddie Deakin in The Ghost Train. The play, which ran in London for 655 performances did less well on Broadway, and closed after 61 performances. Blore remained in the US for the next seven years; his Broadway roles were Reggie Ervine in Mixed Doubles, Sir Calverton Shipley in Just Fancy, Sir Basil Carraway in Here's Howe, the King of Arcadia in Angela, Captain Robert Holt in Meet the Prince, Lieutenant Cooper in Roar China, Bertie Capp in Give Me Yesterday and Roddy Trotwood in Here Goes the Bride. In 1932 he toured as Cosmo Perry in The Devil Passes, before returning to Broadway to play the waiter in Cole Porter's Gay Divorce, which starred Fred Astaire and Claire Luce.
Gay Divorce ran for 248 performances, closing in July 1933, to allow Astaire and Luce to go to London to play in the piece at the Palace Theatre. Blore and Erik Rhodes from the Broadway cast also appeared in the London production, which ran for five months. This was Blore's last London stage show. As The Times put it, he joined "the select company of English actors who were persuaded to journey to California" to appear in Hollywood films, along with the likes of C. Aubrey Smith and Ronald Colman.
