The Royal British Legion is aiming to boost its Poppy Appeal by releasing a fund-raising single - of silence.
The novel idea includes a silent single and video with no music, just occasional background noise.
The video features celebrities from the world of music, sport and politics, including David Cameron, observing a two-minute silence.
The legion hopes the release will help it beat last year's record-breaking appeal total of just under £35m.
Legion spokesman Liam Maguire is optimistic that the single will galvanise people into donating.
He said: "Where have you seen the prime minister and the lead singer of Iron Maiden in the same music video together?
"The reaction on Facebook has been amazing; we've had over 3,500 people sign up in the last 24 hours, so we're hoping the reaction is just going to be huge."
The Royal British Legion, the UK's biggest forces charity, has set a target of £36m for this year's appeal, helped by the "silent" single which it is hoping will get to the number one slot in the charts in time for Remembrance Sunday.
Extra staff have been taken on at a factory in south-west London where volunteers and former service personnel make thousands of poppy wreaths, crosses and posies by hand.
