I dunno Keith. I was doing a gig in Nottingham in a pub, and knowing next to nowt about anything, I was playing and singing On the One Road. The landlady rushed up to me and insisted that I stopped immediately in case her patrons and customers (whom presumably she knew) started fighting.

I was re-telling the incident to Bob Stokes (The Dublin Busker) and he said, that's a rebel song...? I never knew that! we all used to sing it when we were being marched to the swimming baths in a crocodile, when we were little kids...

I don't think the intention to inflame is always there with the song, or with the term proddy dog.
