She's looking in the eye   Of a mind made up   That the pain will last forever      And he's headed for a heart   All closed up, will you ever open up?   She said, "Never"      What is the secret   To keeping your head and your promises?      Oh, "I'll mend your broken heart", she said   Under one condition   If I lift you up, you'll never let me down   Darling under one condition      She stares at the sky, wondering why the night   Isn't telling her, believe in him   If he could only read to her the pages of his heart   She could see they feel the same      Learning the secret   To keeping their heads and their promises      Oh, "I'll mend your broken heart", he said   Under one condition   If I let you in, you'll never push me out   Darling under one condition   And this is my one, this is my one condition      He's getting closer and she's getting closer   Just one more question, one more answer   It was all they ever wanted      Oh, "I'll mend your broken heart", she said   Under one condition   If I lift you up, you'll never let me down   Darling under one condition      Hear me say, this is my one condition   That if I let you in, you'll never push me out   Darling under one, darling under one condition   I'll mend your broken heart, but darling under one condition   If I lift you up, you'll never, don't let me down
