The Boswell Sisters soon appeared in films during this time. They sang the lively "Shout, Sister, Shout" (1931), written by Clarence Williams, in the 1932 film "The Big Broadcast", which featured Bing Crosby and Cab Calloway. The song—one of the sisters' signature tunes—was described in a November 2011 issue of the music magazine "Mojo" as "by no means as archaic as its age." They sang their 1934 song "Rock and Roll" in the film "Transatlantic Merry-Go-Round", bringing with them an early use of the phrase "rock 'n' roll", referring in the song to "the rolling rocking rhythm of the sea".
