We ourselves don't publish them, however, they are in the public domain in a couple of Folkplay publications (from a good few tens of years ago now) following their 'collection'. As were many of the UK's traditions. As a result many traditions in the UK owe a lot the the collestors and the publishers as we all know, whether song music, dance or play. We have to be appreciative of that otherwise we would not be where we are with the Warburton Play totally in our hearts.
Whilst they are in the public domain we therefore cannot stop anyone using them. However we feel the words now belong to Warburton once again and as the Play is 'living' following its period of dormancy we ask people to respect the text as 'they' would ask others to respect their own local texts/traditions or whatever.
The best way of hearing the words is to come and see the Play itself :-)
