"Too-Ra-Loo-Ra-Loo-Ral (That's an Irish Lullaby)" is a classic Irish-American song originally written in 1913 by composer James Royce Shannon (1881–1946) for the Tin Pan Alley musical Shameen Du. The original recording of the song, by Chauncey Olcott, peaked at #1 on the music charts. The song was brought back to prominence by Bing Crosby's performance in 1944's Going My Way. Crosby's single sold over a million copies and spent 100 weeks on the Billboard music charts, where it peaked at #4.
