Political songs have been with us for a long time - someone mentioned Lilibulero - the song that in 1689 was said to "have sung a king (James II) out of three kingdoms" - probably the most influential song ever composed.
Andrew Fletcher of Saltoun (Scottish patriot and anti-Unionist - 1655-1716) had it right when he said in 1704:
"If a man were permitted to make all the ballads, he need not care who should make the laws of a nation".
In my experience the only political songs people really object to are the ones they disagree with.
