Curing an Earworm With the First Phrase of “You Can Fly”

The music behind “Think of a wonderful thought / any happy little thought” is both familiar enough and unstructured enough that it will fill the part of the brain that gets hung up on catchy music but won’t get stuck itself.

I suspect there are other first phrases to mid century children’s music that might work, but mostly I remember the catchy parts of songs and not their strange, arhythmic introductions.
