The next big screen remake of THE SHOP AROUND THE CORNER was a big box office hit in the 1990s. It was the romantic comedy YOU'VE GOT MAIL starring Tom Hanks and Meg Ryan.
Another musical comedy utilizing that Fox formula was 1946's THREE LITTLE GIRLS IN BLUE. This film introduced moviegoers to blonde Broadway musical star Celeste Holm. Blonde June Haver co-starred.
Charles Smith is in THREE LITTLE GIRLS IN BLUE. He was paired with dancer Vera-Ellen. Although both their singing voices were dubbed, they still stand as the two film actors who introduced a new song written for the movie. A good song, it didn't really click with the public until Frank Sinatra recorded it about ten years later.
Here are the dubbed Charles Smith and Vera-Ellen introducing it. Charles Smith -- he was never a star but, man, he did some great stuff with the roles he got. He was really proof of the old saying, "There are no small parts...only small actors." Enjoy the song. It's "You Make Me Feel So Young".
