David Guetta's previewed a new song with Sia

Good news for fans of low-quality audio record­ings and oppor­tun­istic rereleases: David Guetta's 'teased' a new song with credible song­stress Sia.

A phone recording of a recent gig, this clip sees Guetta premiere a song with Sia, rumoured to be called 'Falling To Pieces', from the inev­it­able re-release of 'Nothing But The Beat'.

As usual, this'll probably have dis­ap­peared off YouTube within a matter of hours so don't hang about etc.
