Another of the moments in my book, 101 Must-See Movie Moments, is this performance by Stella Stevens from “The Courtship of Eddie’s Father.”  She’s  shy girl who was too nervous to perform in her beauty queen competition.  When her date, played by Jerry Van Dyke, persuades a jazz group to let her sit in, everyone is surprised.

And similarly, Kay Kendall in the delightful “Genevieve.”  (That’s Kenny Baker’s trumpeting, by the way.)
