Hello everybody.

I am trying to find a song by music video because all I remember is what happeneds in the video.

There is a girl in a yellow dress I believe. And they're at a school dance, in what seems like high school.
Then at the end the gym floor somehow opens into a pool and they all jump into it..

That's all I remember. If you can help I would be much obliged :)

And thank you for taking the time to read this.
I hope you can help me.
