Question: As an antique myself, I naturally gravitate to the movies of the '40s, and I've been searching all over for a movie about a county or state fair that included a singer, Mel "the Velvet Fog" Torme, who sang a soliloquy about "Mrs. Perkin's marvelous mincemeat pie that's as pleasing on your stomach as her daughter is on your eye." Please tell me if you can help an old woman reclaim part of her youth.
Answer: I'm not absolutely sure about this one, but I think you might be looking for So Dear to My Heart (1948) a combined live-action/animated film about a farm boy (early Disney child-star Bobby Driscoll), who raises a black lamb in hopes of winning a blue ribbon at the local fair. Mel Torme and Robert Wells wrote a song called "The Country Fair" for the film. Unfortunately, I've never seen the movie and I can find neither lyrics to "The Country Fair" nor more than a sample of the song, so I couldn't check them against your recollection.
