Katy Perry, Lorde, and various other pop people will be having a singsong at 'Glasto'

Lorde (!), Katy Perry (!!), Tove Lo (!!!), Craig David (!!!!), Goldfrapp (!!!!!), Halsey (!!!!!!) and — you know it — Emeli Sandé () have all been added to the lineup for this year's Glastonbury Festival.

As you well know the head­liners are guitar-bothering Radio X pleasers Radiohead, Foo Fighters and Ed Sheeran, but as any fool with a Twitter account will tell you, 'it's not about the head­liners' etc etc.

So here's a more extensive lineup on a fancy poster embedded in a tweet:
