Bob Weir will appear and perform on The Late Late Show on February 5. Presumably, the talking point will be the Fare Thee Well shows in Chicago over the fourth of July weekend that will see the surviving members of the Grateful Dead reunite for three shows alongside Trey Anastasio, Bruce Hornsby and Jeff Chimenti. John Mayer will serve as guest host for the show.

Mayer has his own Grateful Dead pedigree, as the guitarist has routinely worked in such GD favorites like “Friend of the Devil” and Dead live staple “Goin Down the Road Feeling Bad.” Mayer also famously foreshadowed the Dead’s potential comeback in 2013.

The Late Late Show airs weeknights at 12:37 AM on CBS.
