Photography taken when people are not posing is such a lovely way to capture life in a moment.
Agree wholeheartedly not something to do, but honest captures always tell a lovely story!
First guy possibly lying back enjoying the music, the busker looks a very happy fellow sharing what he offers best, music to make the day a little better for all.
Last guy looks perplexed, slightly confused, perhaps like me he does not like cities :)
