Hey once upon a younger year When all our shadows disappeared
The animals inside came out to play
Hey, went face to face with all our fears
Learned our lessons through the tears
Made memories we knew would never fade
One day my father he told me
" Son don't let it slip away"
He took me in his arms I heard him say (hey)
"When you get older your wild heart will live for younger days
Think of me if ever your afraid"
He said, " One day you'll leave this world behind
So live a life you will remember "
My father told me when I was just a child
These are the nights that never die
My father told me

The Nights- Avicii

That's only part of the song I highly recommend you listen to it :D
