Young at Heart Billy Squier

So you're out to change the world
You can do it none too fast
You don't want to see your future
Wash away into the past
Now a change is gonna come...
Say it's written on the streets
But there's a monkey on your back
...Try to put him on a shelf
And you try to find in others
What you hide inside yourself

And you worry 'bout the war
And you try to understand
But forget about tomorrow
When you're playin' in the band

Stay young at heart
Stay young at heart

Now you've been around the world
Seen the shape of things to come
You begin to feel the damage
From the crazy things we've done
Now the lines are overdrawn
...See 'em bleedin' down your face
And there's a sore and scary monster...
She's-a comin' after you
