On 25 January 1964, after returning to the hotel from a show, Beatles manager Brian Epstein informed them that "I Want to Hold Your Hand" reached number one in the United States on the Cashbox Top 100 chart. On 1 February, it went to number one on the Billboard Hot 100. From this point forward, Epstein focused on promoting the Beatles to the international market. Otto Demmlar, a producer of the German sub-label of EMI, , conceived the Beatles recording songs in German. Odeon Records insisted with Epstein and Beatles producer George Martin that if they wanted to sell more records in West Germany, the band would need to rerecord their biggest songs in German. At that time, recording unique versions for foreign markets was a standard practice. Odeon sent Luxembourger Camillo Felgen, a popular presenter from Radio Luxembourg, to make translations and meet Martin and the Beatles in Paris. Felgen initially translated both sides of the original "She Loves You" single, with the A-side becoming "" and the B-side "I'll Get You" becoming "". Beatles writer John C. Winn translates this back to English as "Happy like never before". Because it was a more recent hit, "I Want to Hold Your Hand" replaced "I'll Get You" and became the prospective A-side of the single, with Felgen translating the title as "". Beatles writer Kenneth Womack translates this back to English as "Come on, give me your hand" while Winn translates it as "Come, give me your hand". Felgen translated under several pen names, including Jean Nicolas, Heinz Hellmer and Lee Montague. The credits on "" are Lennon–McCartney–Nicolas–Hellmer while the credits on "" are Lennon–McCartney–Nicolas–Montague. Musicologist Walter Everett writes that both translations take great liberties. He singles out the chorus of "" in particular, which became, "" These lyrics translate to English as: "She loves you / yeah, yeah, yeah / for with you alone / can she only be happy." In his book Revolution in the Head, Ian MacDonald says, "The German rewrite didn't go so far as insisting on ''." Womack writes a more direct translation of "I Want to Hold Your Hand" would be "".
