What song is going through my head?

For some unknown reason, the song, "Roses are Red" by Bobby Vinton, is going through my head...the really sad one, when he meets the girl later in life and says (well, almost cries), "Is that your little girl? She looks a lot like you...". That has got to be the saddest. To meet your unrequited teenage love later in life...or maybe I'm just more sentimental than I like to think...
