I...don't know why, but the beginning of this song always makes me think of katy perry?

Okay, so we have something that felt vaguely 50s inspired, moved on to mary poppins, had moment of Peter Pan meet Pinoccio, and then...singing in the rain? All I have is confusion and the conviction that, if Brendon Urie were to be the next Doctor, he would go through time and reenact musicals. that is all.
