So you're the BBC producer for Glastonbury, what do you do when the band's lighting engineer decides to wash the stage with red and green light (two of the least camera ready colours) for their whole set?
Well you improvise and I've never seen it done better - or represented an artist so well as I saw the Chemical Brothers headline set on the Other Stage at Glastonbury this year.
This one and this are a particularly nice ones too from their 2007 Glastonbury appearance.
You can still see highlights of The Chemical Brothers' set at Glastonbury or other artists on BBC iPlayer. And if you've got Virgin Media (like I have), you may still be able to get some On Demand.
