Orchestra arrangement for a song from The Simpsons (not the theme)?

Question:

Orchestra arrangement for a song from The Simpsons (not the theme)?

There is an episode of the Simpsons (I'm not sure which season or episode number/name) the family goes on a nature walk into a cave and fall through a hole. Homer is stuck and while Marge, Maggie and Bart go to find an exit, Lisa tells Homer a story. When Burns and the man from Texas are on a scavenger hunt, a song is played and from what I hear, it sounds like a string orchestra arrangement. It is also played at the end credits. If anyone knows the name or composer of this song, I would greatly appreciate it.

Best Answer - Chosen by Asker: That would be "Hoedown" from "Rodeo" by Aaron Copland. The episode's title is "The Seemingly Neverending Story" and it's from Season 17.
