Some famous names are passionate about Scotland and have added their names to a list asking Scottish voters to keep the country a part of the U.K. The Rolling Stones’ Mick Jagger, Patrick Stewart and Sting are just three of the 200 names of celebs who signed the letter.

According to NME, in a little over a month, voters will be asked to vote on an independence referendum that will determine if the country will be breaking away from the U.K.

“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 U.K. and about our collective place in the world,” Dan Snow and Tom Holland wrote on their website, letsstaytogether.org.uk.

Snow and Holland are historians who organized the Let’s Stay Together campaign, and they said that their message is for those who “value the bond of citizenship” with the Scottish.

Scotland was actually its own country until 1707, when it was united with England. In 1927, the United Kingdom of Great Britain and Northern Ireland was established and Scotland has been a part of the U.K. since then (along with England, Wales and Northern Ireland).

The campaign’s goal is to give a voice to those who are not allowed to vote — including many English citizens. Judi Dench, Helena Bonham Carter, Patrick Stewart, Stephen Hawking, Simon Cowell, Tom Daley, Eddie Izzard, Andrew Lloyd Webber and Dominic West are among the other celebs who have signed the letter. Michael Douglas is reportedly the only non-Brit to have signed the letter.

Although the main members of the British royal family are usually pretty vocal about their causes — especially where it relates to their history — they have not yet signed the petition.
