According to a 1931 article, before “Boop-Boop-a-Doop” the most popular meaningless sound to interject into songs was “Ta-Ra-Ra-Boom-De-Ay”a song by the same name that goes way back to 1890s. The song became widely known in the version sung byLottie Collins in London music halls in 1892. The song’s authorship was disputed for some years. It was originally credited to Sayers, who was the manager of the George Thatcher Minstrels; Sayers used the song in his 1891 production Tuxedo, a minstrel farce variety show in which “Ta-Ra-Ra Boom-De-Ay” was sung by Mamie Gilroy. However, Sayers later said that he had not written the song, but had heard it performed in the 1880s by a black singer, Mama Lou, in a well-known St. Louis brothel run by “Babe” Connors.
