I'm fifteen for a moment
Caught in between ten and twenty
and I'm just dreaming
counting the ways to where you are

I'm twenty-two for a moment
and she feels better than ever
and we're on fire
making our way back from mars

Fifteen, there's still time for you
Time to buy and time to lose
Fifteen
There's never a wish better than this
When you only got a hundred years to live

I'm thirty-three for a moment
I'm still the man
but you see I'm a they
A kid on the way, babe
A family on my mind

I'm fourty-five for a moment
The sea is high
and I'm heading into a crisis
chasing the years of my life

Fifteen, there's still time for you
Time to buy and time to lose yourself within a morning star
Fifteen, I'm alright with you
Fifteen
There's never a wish better than this
When you only got a hundred years to live

How the time goes by
Suddenly, you're wise
Another blink of an eye, sixty-seven is gone
The sun is getting high
We're moving on...

I'm ninety-nine for a moment
Dying for just another moment
and I'm just dreaming
counting the ways to where you are

Fifteen, there's still time for you
Twenty-Two, I feel her, too
Thirty-Three, you're on your way
Every day's a new day...

Ooooooh
Ooooooh
Oooooooooh

Oooh

Fifteen, there's still time for you
Time to buy and time to choose
Hey, fifteen
There's never a wish better than this
When you only got a hundred years to live
