Too-Ra-Loo-Ra-Loo-Ral (That’s an Irish Lullaby)” is a classic Irish-American song that was originally written in 1913 by composer James Royce Shannon (1881–1946) for the Tin Pan Alley musical Shameen Dhu. In 1944, Bing Crosby released a version of the song which brought it to public attention again. First performed in the film Going My Way, it was subsequently released as a single that sold over a million copies.
