The German girl group the Sweetles was a short-lived Beatles tribute band that cashed in on the Beatles boom. In 1964 they had a top forty hit in Germany with the single “Ich wünsch’ mir zum Geburtstag einen Beatle” (I Want A Beatle For My Birthday).
The Sweetles were the brainchild of German songwriter Christian Bruhn, who also co-wrote the tribute song. On the cover you can see four girls – check out the fancy wigs and guitars – to make the Beatles tribute idea complete. But on the song there are only three singers: Peggy Peters (real name Christina Zakewski), Charlotte Marian (real name Charlotte Bischoff), and actress-singer Monika Grimm.
Charlotte Marian was married to songwriter Christian Bruhn. Peggy Peters later continued her singing career under the name Tina Rainford.
