I wrote a dozen or so songs including this one for a Scottish Republican LP, sung by Nigel Denve and sleeve notes by Hugh MacDiarmid in 1966. It was intended for a Scottish audience as I have no truck with English MPs. I used fairly well known tunes as some folkies then as now find written music difficult to read. The choice of tune was to make the song instantly singable as Off to Dublin ... was well known in Scotland then and the parody is obvious. I repeat, the song was written almost 45 years ago.
