I purchased their official annual today (I'm so cool), and for anyone interested, it's actually really good!
Has tones of unseen photos, obviously from the same photoshoot they did for the Headlines Tour brochure. It has photos they did aswell for the plasma screens for that tour, like during the intro (when they are taking pics), they have photoshoot images from that - and stunning photos of them all swinging on swings - Frankie's is phenomenal.
Also includes loads of behind the scenes stuff, and a full list of discography including all their songs, from bsides, to album tracks, etc etc. Tones of interviews, and them highlighting their favourite moments of the last 12 months.
Definitely worth the £3 ha!
