In 1947, too, Locke released "Hear My Song, Violetta," which became forever associated with him. "Hear My Song, Violetta" was based on a 1936 tango "Hör' mein Lied, Violetta" by Othmar Klose (13 October 1889 – 24 January 1970) and Rudolf Lukesch. The song "Hör' mein Lied, Violetta" was often covered, including by Peter Alexander and was itself based on Giuseppe Verdi's "La Traviata". His other songs were mostly a mixture of ballads associated with Ireland such as "I'll Take You Home Again, Kathleen", "Dear Old Donegal", "Galway Bay", "The Isle of Innisfree" (the theme song from the film "The Quiet Man"), and another Dick Farrelly song, "The Rose of Slievenamon," excerpts from operettas including "The Drinking Song" from "The Student Prince", "My Heart and I" from Richard Tauber's operetta "Old Chelsea", and "Goodbye" from "The White Horse Inn", along with familiar favourites such as "I'll Walk Beside You," "Come Back to Sorrento," and "Cara Mia."
