Graham Nash and David Crosby have contributed vocals to a David Gilmour-penned track on the upcoming Pink Floyd album, The Endless River. Ultimate Classic Rock reports that Nash revealed the info during an interview with VH1 Radio Network, saying “We went down to sing on this particular song that he wrote about friends that had died…It’s a beautiful song, too — beautiful.”

The new track won’t mark the first time that Nash and Crosby have collaborated with Gilmour. The pair also added their voices to the title track for the Pink Floyd guitarist’s 2006 album On An Island.

As previously reported, Pink Floyd recently confirmed that they will be releasing their first album since 1994, The Endless River, in October. The new LP, which is co-produced by Gilmour, will primarily feature ambient and instrumental music based the band’s 1993/1994 Division Bell sessions.
