American stars We Are Scientists have joined forces with Northern Irish rockers Ash to record a song for charity.
The two bands are teaming up for a cover of songwriter Robert Manning's track Washington Parks to raise money for the Multiple Sclerosis Society.
We Are Scientists bassist Chris Cain tells The Examiner, "The concept of the song is that if you listen to it on headphones or stereo, the musicians of Ash are on the left channel and all the We Are Scientists guys are playing it in the right channel. We're playing the same song essentially but in different ways."
Manning, who suffers from the debilitating disease, is selling the collaboration via his official website.
Singer Ed Harcourt and Emmy the Great have also recorded tracks for the project.
