Young at heart   Young at heart      Young at heart   Yet what a start   Old before their time   They married young   For love at last   Was their only crime      How come I love them now ?   How come I love them more ?   Young at heart   You're so young at heart      Young at heart   Yet not a chance   To be a child at all   They told us tales   They told us lies   Don't they know   The shouldn't have told us at all      How come I love them now ?   How come I love them more ?   When all I wanted to do when I was old   Was to walk out the door      Young at heart   You're so young at heart   Young at heart   You're so young at heart      How come I love them now ?   How come I love them more ?   How come I love them now ?   How come I love them more ?   How come I love them now ?   How come I love them more ?   When all I wanted to do when I was old   Was to walk out the door      Young at heart   You're so young at heart   Young at heart   You're so young at heart   Young at heart   You're so young at heart
