That's 37 I heard piano music and singing rising above the 38 of the people and the traffic. I walked a little slower 39 I could find out where it was coming from. 40 the crowd I saw a young lady sitting at a piano with a 41 next to her, singing songs about love.

My heart was touched by a 55 soul.
