They were taking a break after an impromptu session at the world's biggest traditional musical festival, this year in my home town, Sligo, Ireland, whose landscape was inspired much of the work of the great poet, William Butler Yeats. I spent hundreds of shots which I wouldn't put up here, and then, this evening, on my way home, shattered and ''shot out', I rested for a pint in the door of a packed pub -and there they were, but they could have been anywhere. I just chanced upon them. It's the serendipity of street photography.
