In addition to writing the English words to Lili Marlene, Tommie Connor wrote I Saw Mommy Kissing Santa Claus. Jimmy Boyd recorded it at the age of 13 in 1952, and it sold a million records. (I originally had the singer as "Tommy Boyd" - thanks to Jon M. Schumacher for pointing out the error.)
Jimmy Boyd went on to record singles in the mid-fifties on Columbia and Capitol. He recorded with both Rosemary Clooney and Frankie Laine. He also recorded on the Imperial, Take Ten and Vee Jay labels in the sixties. Thanks to Jon M. Schumacher for this information about Jimmy Boyd's career.
