help me find a song/ when is the talent show in the Ackerman ballroom supposed to be for?

So I was eating my lunch in bench outside ackerman ballroom and I can hear some dude singing "And she's pulling her tight.... and somthing somethiIINNNGGGG- Runaway, Runaway, Runaway, Runaway" and it's like an Indie guitar song, but then the ending builds up and it's like instrumental and I think I heard some harmonica in the background?

Anyways, what is that song?! 😭 I don't have social media so I couldn't stalk any Ackerman Ballroom talent show events.

If you know the song, lmk. If you know the talent show date, also lmk pls and ty.
