I Wonder Who’s Kissing Her Now

I had a friend; he’s gone a long time ago, but when I first met him, we went on a long tour. He didn’t go into details, but I understood that he was unlucky in love and his girlfriend had left him. So he insisted that we should play this tune. I regret that I didn’t know it at the time so it never happened, but I play it now, think of him, and wish that he could join with his soprano sax.
