"Falling in Love Again (Can't Help It)" is the English language name for a 1930German song composed by Friedrich Hollaender as "Ich bin von Kopf bis Fuß auf Liebe eingestellt" (literally: "I am, from head to toe, ready for love"). The song was originally performed in the film Der Blaue Engel (English translation: The Blue Angel) by Marlene Dietrich, who also recorded the most famous English version, which became her anthem. The English lyrics were written by Sammy Lerner, though they do not include a translation of the original version's most erotic verse; when the English version is sung, the first verse is simply repeated. The song is sometimes co-credited to Reginald Connelly.
"Falling in Love Again" was covered live by The Beatles in 1962, in their early Hamburg touring days. It is the only recording from the album The Beatles, Live at the Star Club, in Hamburg, 1962, with Paul McCartney singing lead vocals, as well as on the album First Live Recordings. The Beatles had updated the melody to a rock-'n'-roll style, with a change of lyrics.
