The blond actor, Jimmy Bates, who played Claude, was the same actor Fred Astaire dances around in the toy shop in the 1948 musical Easter Parade (1948).
When Bud's pals Claude and Joe tease him when he is at his locker, Bud starts to sing about Dora. Joe, the brunette, calls Bud "Caruso," which is an allusion to the Italian opera singer Enrico Caruso.
Susan Odin plays Dora, an assertive girl who has a crush on Bud in this story line. In Young Love (1958) from season 4, Susan Odin also plays a girl who has a crush on Bud, but that time she plays a different character named Bernice, who Bud calls Bernie. Bernice is the opposite of Dora in that she is shy and passive in her pursuit of Bud.
Susan Odin played one of Betty Hutton's siblings in the 1950 MGM musical [link-tt0042200]. She played the uncredited role of Jessie Oakley, and she can be best seen in the musical number "Doin' What Comes Naturally."
