Yes, I agree with the stuff about the mix, Ketamine. It's a pity because I was quite excited hearing it at the 6Music session and thought it would be an obvious single.
As for not finishing it, well, okay you got me there, but that's very much how it sounds to me. It starts really well but after the first chorus it just fizzles out - the same lyrics repeated over and over and no new musical ideas. The opening verse melody never gets repeated, which is a pity because it's a strong hook. That thumping Give-Peace-A-Chance rhythm is infectious but it's not enough to carry it when the rest is so thin.
Oh, and the lyrics stray into his dodgy politics territory, which I so wish he wouldn't do . I really don't like 'Presidents come, presidents go, the damage they do' - it's meaningless twaddle, it lacks insight and seems to lack any real thought or effort. In my opinion.
