Melody of an Unexpected Encounter

I was walking with someone along the pedestrian part of the street, next to the facades of houses. On our way, we encountered an elderly couple: a man and a woman. The woman held a strange musical instrument, resembling a synthesizer, and played the same melody from a Queen song. The man was collecting money. I approached them to give them coins, but I couldn't do it. In the end, I put the coins directly into the man's mouth.
