They have power, astonishing power no doubt, but not even Girls Aloud can change the season. Junior and I ignore the Christmas tree for three or four minutes and put some effort into imagining it’s a July morning and we’re shaking like cool lemonades. She gets better results than me, because she’s not sitting there tackling the existential question of how on earth one can shake like a cool lemonade. Is it the bubbles? Or is it the movement of the liquid when the ice cubes are dropped in? Perhaps the lemonade shakes because Nadine, Kimberley et al are holding it while they sashay around the CD:UK stage? Like “I was 21 years when I wrote this song, I’m 22 now but I won’t be for long”, this latter theory would beg the question of how the performance came before the lyric.

We’re getting bogged down. Junior likes the song, and how could she not? It has at least two different bridges, a half-rapped middle eight and an unexpected ad lib at the end instead of a thoughtless repeat of the chorus. And it has “ba ba ba”s, making it a contender for First Song That Junior Will Actually Sing Along With.

It has competition from ‘Hey Jude’, ‘Telegram Sam’ and the Pearl & Dean theme.
