Which version of Carly Rae Jepsen 'Call Me Maybe' ?

Hi all

This audio was recorded on a digital camera's video.

Try to ignore the saxophone as that was a live performance over the top of the DJ.

It is Carly Rae Jepsen 'Call Me Maybe', but it sounds a much harder version that I've heard, and the crowd were loving it. that harder bit starts at 6 seconds.

Does anyone recognise what mix of it this is, or am I just being fooled into thinking it's a harder version by the awful sound quality on the camera's video?

It sounds like the song "Call me maybe" from Carly Rae Jepsen, but using a saxo.

Cheers,
