The Input: Do you entirely equate "left-wing political" to "folk"? If so, that song is folk. If not, maybe it is, maybe it isn't.   What's the tune? Has it been sung by different people since the Thatcher years? I've seen equally direct words used in a pop song: just having the "right" attitude isn't enough.

Personally, I think "folk" is a lot wider than "left-wing protest". That is partially how I came to take an interest in the field, but only partially.
