Bob Weir recently welcomed Bert Keely into his home studio to record a special duet of John Lennon’s classic “Imagine.”

Weir supplies guitar and vocals on the pensive track, while Keely assists on bass, and it will appear on Keely’s upcoming box set Circle Back! (out June 4).

According to the musicians, it was recorded in memory of their mutual friend Richard Newton.

Another Weir appearance on Circle Back! includes a “Jack Straw” > “Playin’ in the Band” > “Queen Jane Approximately” jam clocking in at 28 minutes.
