Top of the Pops, 10th September 2015

We're very pop this week, with Demi Lovato, Little Mix, 5 Seconds Of Summer and new number 1 Justin Bieber providing the bulk of the show. Bieber also doubles up to fill in for the dashing (but again unavailable) Chris Brown on Pia Mia's Do It Again.

Friend of the show The Weeknd has released his album and invaded the lower reaches of the chart with no fewer than four mini-hits; he performs two of them alongside continued smash Can't Feel My Face. This week's archive dredge is Elton John - why is he back in the chart?
