We have a similar Wibberly Wobberley Walking Parade tradition in south Wales. Some say it travelled here with the Irish during the industrial revolution, others say that it was always here but as a more individual pirsuit. The temperance movement, and the non-comformist churches tried their best to put a stop to it but there's been a recent revival, particularly in urban areas. The best time to observe it is between 2 and 4 in the morning in Cardiff in Caroline Street (or Chippie Alley as it has become known) and the surrounding area.
It's good to see the youth of the day keeping up our honourable traditions.
