It’s a rare enough event, so we like to celebrate it, when Sputnik’s favourite Aussie pop whore Davey Boy‘s tastes overlap with anybody else’s.

It’s even more unusual when two of those rare events collide, but as it happens Davey and I share more than just a name: we both have a keen appreciation of the full-on badassedness of P!nk and the slightly less full-on glamness of Idol pretty boy Adam Lambert.

Here’s the collision – Lambert’s 2010 hit ‘Whataya Want From Me’ was co-written by P!nk and recorded for her 2008 album Funhouse. It didn’t make the final cut, but Lambert gave it a key platform on his debut album For Your Entertainment. Now P!nk’s original demo has emerged and it’s virtually identical – the arrangement is the same, possibly (probably) the same exact instrumental track, but obviously with P!nk’s voice on top.

Being virtually identical, there’s not an awful lot to tell between the two tracks, yet it’s clear even from the rough mix that Lambert’s singing really makes the track – in fact, from the demo it’s pretty clear to see why it wasn’t included on the final mix of Funhouse. In any case, it’s a handy little insight into the fine margins that separate a really good pop single from just another cut on the studio floor.
