Why shouldn't that song be by MacColl? There are quite a few people who took some time to wake up to the evils of Stalinism! And you can't just take a song back - once you've published it (even by just singing it) it stays public!

For ten years now I've known a couple from Glasgow - a railwayman and a housewife, both now eighty - who used to tell me, with eyes shining, about the days when they took the Daily Worker round the houses where they lived, their visit (visits?) to the Soviet Union, and the time when the Party was their spiritual home, and bemoan its fall from grace just because the Soviet Union fell. (Incidentally, I happen to agree with them on the point that this fall does not necessarily discredit socialism as a whole, as many people seem to believe.)
