There's a thing you don't do with 4,000 people watching.

As a perform, you perform.

When things go wrong... you improvise. After an hour of appalling sound and plagued by constant crackling from a broken cable... Thom Smith of Editors takes to a solitary rendition of “Smokers Outside The Hospital Doors”. He then apologises for the poor sound (an hour after everyone first noticed it), and says they'll be back in 2 minutes.

The two minute break turns into 30 long minutes. The band – who've also recently performed several acoustic songs – had to fill the time by restarting the whole sound desk, and that takes time. Tom throws the setlist into the crowd in frustration and then disappears. The technicians play music over the PA. A few hundred people leave early. The band come back 5 minutes later, get four bars into “Bricks And Mortar”, and give up, leaving the stage. They come back a second time, and they don't even start a song. Then they leave the stage again. And they don't say anything to us. I appreciate this is really difficult if the sound stops working completely and sometimes there's little you can do.

If you can't sing the acoustic songs – please explain why.

It doesn't feel good for there at an empty stage playing Radiohead songs during an unscheduled half hour intermission in the gig. A lot of people left early tonight. We're human. We get stuff breaks. A great shame, because it was a great show otherwise.

EDIT : udpated after clarification around the circumstances offstage. Apologies for losing my temper.
