Broadsides developed in many ways with publishers, printers. singers and sellers all responsible for making changes.

They were all in the business of making money and providing material that could be sold .. Songs were changed or adapted to cater for the preferences of the region and the client.

This is why you will get the same song printed in different ways in different areas and where the oral tradition played as much a part in developing songs in the past, as it does today.

I have always believed that there is no such thing as a definitive version of a folk song unless you have proof of its originator.
