America's Got Talent

I am a bit vague about the name of the act but it was the family with the little girl and the lovely dogs.
What I would like to know is the name of the song they played during their routine. A few of the words were ' you're in and you're out, you're out and you're in' Does anyone know the title of the song and who sings it (I'm not up on pop music but it was very catchy)

[Barsel]

Is it this?

[Barsel]

Katy Perry sings this but I don't know if this is her.

[fiction-factory]

The song is Hot n Cold which Katy Perry sang- hard to tell if it's her or a good cover

Thank you both very much - very much appreciated !
