Icelandic pop icon Björk has taken to Facebook to declare her support for the Yes campaign the day before Scotland votes on independence. 

The singer changed the lyrics of her 2008 single "Declare Independence" to address Scottish voters, urging them to "start your own currency! Make your own stamp! Protect your language". It's an emphatic message to a country that will go to the polls in what looks to be an incredibly close referendum. 

Here's an excerpt of her lyrics:

s c o t l a n d !
s c o t l a n d !
s c o t l a n d !
declare independence!
don't let them do that to you!
declare independence!
don't let them do that to you!

You can read the rest of the song over on her Facebook page. 

"Declare Independence" was recorded for Björk's Volta album. The song was originally dedicated to the Faroe Islands and Greenland, which are currently ruled by Denmark - the same country that once governed Björk's native Iceland. 

This isn't the first time Björk has commandeered the song to suit other national struggles for independence – in 2008, she came under fire from Chinese authorities for shouting "Tibet, Tibet" during her performance of the song.
