Stephen Stills (Crosby, Stills & Nash) and Judy Collins recently debuted “Judy,” the second track from their forthcoming collaborative record Everybody Knows  which is due out September 22.  Stills wrote it 50 years ago as a tribute to Collins while working on her 1968 album Who Knows Where The Time Goes?, in which he played guitar and bass on.

Just after the session wrapped, Stills paid the engineer to let him record a demo of the track in that same studio, but left the tapes behind. They were considered lost for decades. That following year, he would pen his better-known tribute to Collins, “Suite: Judy Blue Eyes”. The song was named one of the 500 Greatest Songs Of All Time by Rolling Stone Magazine.

“Judy” wouldn’t resurface until 2007 on the Stills compilation Just Roll Tape. Presently, Collins and Stills decided to give it a proper duet recording during the Everybody Knows sessions last year in LA.

The new record features many other songs from the duo’s intertwined history, including a cover of Stills’ “Questions” and “So Begins The Task”, as well as Judy’s “Houses” and the aforementioned “Who Knows Where The Time Goes.” The album also features work by both Bob Dylan and Traveling Wilburys.

“As Stills and Collins wind their voices around the song’s incantatory, minor-key melody in a hypnotic, almost spooky, harmony, the depth and gravity of Cohen’s observations gain easier access to the soul.” says NPR Music.

The duo will tour together through the end of the 2017. Find a full list of dates here:
