No video footage to bring you just yet (you'll have to watch Channel 4 on Friday night/Saturday morning) but tonight's secret special guests just played the most astonishing version of this:

I've always thought 'This Is A Low' was Blur's best song - and, to see it performed here, acoustically, by two men who haven't shared a stage for the best part of nine years, backed up by the voices of a by-now majorly sozzled Academy crowd, was pretty breathtaking.

Pete Doherty looked pretty choked up - I spotted him filming it on his mobile.
