Brent Spiner (sings):   Be sure it's true   When you say: "I love you"   It's a sin to tell a lie   Millions of hearts have been broken   just because these words were spoken   I love you, yes I do. I love you   If you break my heart i'll die      Be sure that it's true   When you say: "I love you"   It's a sin to tell a lie         Patrick Stewart (says):   Be sure that it's true   When you say: "I love you, darling"   Bacause, because you know    that it's a terrible sin to tell a lie   So many, oh so many hearts have been broken   And all because, because these words were spoken      Brent Spiner (sings):   I love you, yes I do. I love you   If you break my heart i'll die      Be sure that it's true   It's a sin to tell a lie
