Coldplay are trying to ensure they don't 'go broke' thanks to their latest tour.
The British band are currently completing their Mylo Xyloto Tour around the world, to promote their latest album.
They have been providing audiences with flashing wristbands to wave around during the performances, but frontman Chris Martin has admitted it's been problematic.
'Most of the money we're earning on the tour is put into the wristbands,' he explained.
'We have to figure out how to keep it going without going broke because it's a crucial part of the concert.'
The group ' comprising of Chris, Jonny Buckland, Guy Berryman and Will Champion ' first handed out the arm gadgets in Madrid last October. Since then, around 40,000 fans have got their hands on one.
To cut down on costs, the band considered asking for them back once their performance had ended.
'You have to clean everything in case someone picks up herpes or TB. Our lawyers told us we'd get sued, and having been sued a few times we're not keen on that,' Chris told British newspaper The Sun.
'It's a little self-indulgent but we love the way it looks when there are 15,000 or 40,000 or however many people with all those lights on them. The technology is still very experimental.'
Chris isn't a fan of all kinds of technology though. He becomes anxious when he sees people fiddling with their phones during his shows.
'The only thing I fear is texting. If they are texting they are not enjoying the music,' he said.
