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. Stay young at heart. Stay young at heart. You can't be too wise. So open your eyes. Stay young at heart...yea. Now you're weary from the war. But it's time to start again. And you don't know what you're fightin' for. But you'll fight until the end. Now forget about the future. Don'tcha try to understand. There's no need to fear tomorrow. Just keep playin' in the band. Stay young at heart. Stay young at heart. You can't be too wise. So open your eyes. Stay young...stay young. Stay young at heart.
