I liked the MC Nxtgen Andrew Lansley rap, which was a lot more scatching in some ways, not just because of its gratuitous use of the word "tosser", but largely because it spelled out some specifics about Lansley's relationship to certain interest groups and the perceived consequences of the bill. Quite an achievement, because a lot of political songs tend toward crowd-pleasing tribalism rather than necessarily elucidating an argument. As Fred says, theirs is a song specifically for those who are already convinced, to raise morale, and that has its function, although I think songs to persuade would need to be crafted in a different way. Personally, I'm a bit wary of the "them and us" rhetoric of some of these songs, partly because having seen the nature of politics in the US at close quarters I'm even more desperate to salvage consensus politics in the UK while there's still time. Reeks of fence sitting, I suppose, but then Gladstone was a Scouser too, and spent a lot of the 19th century trying to traverse different interest groups in the messy UK party system. His tradition is also one to be proud of.
