A snippet of Sia’s Leona Lewis demo has surfaced

A snippet of a track written by Sia for Global Songstress Leona Lewis’ ‘problematic’ third album ‘Glassheart’ has materialised.

The clip for ‘Blank Page’ features Sia herself on vocals, but reports last September confirmed that Leona has recorded a version of the track.
