Gareth, Maurice Mann and everyone, see This blue clicky for info on a very lighthearted view of the Rebecca Riots.

There are a few of books on the subject, but the best is probably, "And they blessed Rebecca" by Pat Molloy, published by Gomer Press of Llandysul.

I don't know of any folk songs inspired by the Rebecca Riots (my fault for living on the wrong side of Offa's Dike). Any Welsh 'Catters care to point me in the right direction ?
