Lyrics:

We were circus lights and cannonballs
We were way too high to ever fall
We were fireflies and shooting stars
We were burning up from the start
And we'd say 'are we gonna live forever?
I love you to my dying day'
But sometimes hearts get swept up in the waves

Remember when the night turned up
And the sun went down
If just for a moment
We were falling at the speed of sound
Yeah, the moon, it played a part
Two shadows in the dark
Beating with a teenage heart
Beating with a teenage heart

Would I even recognise your face
If I saw you in a crowded place?
Would your hair still fall the way it did?
Would we laugh and sing like when we were kids, oh

Remember when the night turned up
And the sun went down
If just for a moment
We were falling at the speed of sound
Yeah, the moon, it played a part
Two shadows in the dark
Beating with a teenage heart
Beating with a teenage heart

Yeah, we thought that we would last forever
Thought our love would never fade
Had your hand pressed on the window as you pulled away

Remember when the night turned up
And the sun went down
If just for a moment
We were falling at the speed of sound
Yeah, the moon, it played a part
Two shadows in the dark
Burning like shooting stars
Beating with a teenage heart
Beating with a teenage heart
A teenage heart
Ooh, yeah, beating with a teenage heart
