Dim 1 is the diminished chord on the 1st fret etc. Let me call you sweetheart, I'm in love with you. Let me hear you whisper that you love me too. Keep the lovelight glowing in your eyes so blue. Let me call you sweetheart. I'm in love with you. Only Girl In The World. If you were the only girl in the world, and I was the only boy. Dim1 Nothing else would matter in the world today. We would go on loving in the same old way. A garden of Eden just made for two With nothing to mar our joy. I would say such wonderful things to you. There would be such wonderful things to do. If you were the only girl in the world, and I was the only boy.
