Mick Jagger and Sting among 200 celebrities urging Scottish voters to stay in the UK
Bryan Ferry and David Gilmour of Pink Floyd also back Let's Stay Together campaign
An independence referendum will be held on September 18 which could see Scotland break away from the rest of the UK. The letter, which was organised by historians Dan Snow and Tom Holland, aims to let people in Scotland know that those who have endorsed the message "value the bond of citizenship" with those north of the border.
The letter is part of the Let's Stay Together campaign that aims to give a voice to those who are not allowed to vote in the referendum. A video including some of the figures involved in the campaign, a list that also includes musicians Bryan Ferry, David Gilmour, Andrew Lloyd Webber and Cliff Richard, can be seen above.
"We believe that the key missing message is a positive, emotional one: not telling the Scottish electorate what to do or what not to do, but telling them how we feel about Scotland, about being part of the UK and about our collective place in the world," Snow and Holland wrote on their website.
Other notable Britons who have signed the bill include actors (Judi Dench, Helena Bonham Carter, Eddie Izzard, Patrick Stewart, Steve Coogan) and Olympians (Tom Daley, Steve Redgrave) plus David Attenborough, Stephen Hawking and Simon Cowell.
