In many ways – visual, musical, camp – Scissor Sisters were a shot in the arm for a moribund pop scene. The teen bracket was thriving, sure, mainly through the reality parade, but Jake Shears, Ana Matronic, Babydaddy et al negotiated a glitzy path to the heart of the big record buyer. A crossover triumph. Their showtuny, Elton John-infused (and frankly pretty flimsy) debut album was neck and neck with the more prosaic Keane in the year’s bestselling chart, laying bare 50 Quid Man’s lesser-spotted appetite for gay-as-a-window flim-flammery.

They waved their jazz hands over the parapet with this impudent romp over Pink Floyd’s dour classic. We heard the Bee Gees, KC & The Sunshine Band and – perhaps most of all, but less acknowledged – Frankie Knuckles. What initially appealed as a Night Fever throwback turned out to be a modern house monster with pop bells on, a gleeful destruction of Roger Waters’ puffed-up, jacked-up sense poem, but a destruction somehow executed with poignancy and cheeky respect.

I think it’s respect anyway. The euphoric hand claps after “But you may feel a little sick” don’t suggest much forelock-tugging.

Reactions from Junior tread the thin line between the surreal and Keanely prosaic – “Are they cutting?” “Is it Lily Allen? Is it soldiers?” “Where’s the lady?” Junior’s in the back of the car, but I can hear her clapping along, sending up Pink’s peril and “Uh-huh-uh-huh”ing where called upon. “I sang lots of that,” she tells me as the song echoes away, so there’s your proof. A crossover triumph.

Come on, it’s time to go:
