When Tomorrow is This Morning Again

"Tomorrow is this Morning Again" is a song sung by Candace and Dr, Doofenshmirtz, with chorus by Laura Dickinson, after they discover the power of the "Do-Over-Inator" in "Last Day of Summer".

Lyrics
Doofenshmirtz: They say you only go around once They say that opportunity, it never knocks twice But if there's one thing I can say about the people who say that They don't have this cool deviiiice! (they don't have this cool device!)

Candace: I've never even heard of deja-vu this bad But everything today is so familiar Like the best recurring dream I ever had Like when you know it's gonna happen but it's still gonna feel good If it keeps repeating, I should do something about it I don't know the repercussions if I just let it run If you told me there'd be consequences I wouldn't doubt it But it's tempting just to let it go and use it for fun! (use it for fun!)

Doofenshmirtz: I could get it right Because today I have multiple chances Candace: With just a little foresight My worries will be over soon! Doofenshmirtz: I'll rework my fate Improve my circumstances!

Candace: If I get it wrong Both: this afternoon Doofenshmirtz: I'll get it right today When tomorrow is this morning again! (Yeeaaaaaaah)
