I remember seeing and hearing a very tall , fairly old (45 - 60 ish) Traveller Woman singing at GAA Games in some of the larger venues around Munster, in the early 50s. She had a wire supported money collection bag too. One song I still recall , that she sung, was "Boolavogue". She had a distinctive way of ending the verses by staying on the same note for the words "........far and near".
I remember the Dunne brothers busking in Cork city also. I had no idea that they travelled around the country so much.
