Poor Amy, returning at the height of Lily fever. Comparisons will of course be inevitable, both being feisty females stirring the music world up in more ways than one, but the similarities end there. ‘Rehab’ is a smooth, jazzy track signatured by the line “They tried to make me go to rehab but I said no, no no” (its effect diluted by the fact that she eventually caved in). Wonderful stuff.
