Phish are playing Nashville’s Ascend Amphitheater tonight for their first of two shows at the venue, and the group’s soundcheck just revealed a possible special guest for night one, as Bob Weir joined them near the end.

Weir, who is in town to play the Ryman Auditorium tomorrow night as part of his Campfire Tour, tried out “Walking Blues” with Phish for the soundcheck. The tune is a Weir staple but has never been played by Phish.
