The musical itself is everything you expect from an MGM musical of the late 1940's - rather light on story and heavy on visual style and good music. I've had the advantage of seeing the original movie musical from 1930, at least what's left of it, which is actually the entire film minus the Technicolor finale. That original has the disadvantage of not having the technical advantages in sound recording and camera mobility. However, the original 1930 movie does have the character of Babe being played by the pixie-like Bessie Love of "Broadway Melody of 1929", and she is every inch the mischievious flapper that Joan McCracken just is not. In fact, the coeds in the 1947 film seem very much like they're from 1947, they're just dressed up in the fashions and driving the cars of the 1920's.
In this film, Connie (June Allyson) is tutoring Tommy (Peter Lawford) in French just as in the 1930 version - except there the subject was astronomy. However, there are two big differences here. In the 1947 film, Lawford's motivation for studying French is to win the affection of a beautiful new student. Also, Tommy knows exactly who Connie is, and their attraction builds slowly. In the 1930 film, the first time Tommy sees Connie she isn't exactly wildly attractive, but she is the best student in the subject at the college. Also, Tommy is already enrolled in French, he is just in danger of failing it and not being able to play in the big game. Also notice in this later film the presence of a very young Mel Torme who seems to be standing in for Cliff Edwards from the 1930 version, complete with ukelele.
