When I Fall In Love:The Lettermen. #7 in 1961. #1.( for original.) When I fall in love.....it will be forever.. or I'll never fall in love. In a restless world like this is, love is ended before it's begun. And too many moonlight kisses, seem to cool in the warmth of the sun. #2. When I give my heart....it will be completely.. or I'll never give my heart... And the moment I can feel that, you feel that, way, too, is when I fall in love with you.... REPEAT#2. ADD: is when I'll fall in love with you. A sixties smash from Kraziekhat.
