Sam Bush joined Yonder Mountain String Band for the entirety of their New Year’s Eve show at the Boulder Theater in Boulder, CO last night. The bluegrass legend sat in with the band on fiddle, mandolin and vocals through the two set show, which featured covers of Jerry Garcia Band’s “Reuben and Cerise” and Flatt and Scruggs’ “Rollin In My Sweet Baby’s Arms.”

In addition to last night’s extended sit in, Bush also joined Yonder for a number of songs during their benefit concert for Planet Bluegrass (which suffered severe flood damage back in September) at the Boulder Theater on December 30. That exciting performance also featured guest appearances by Jerry Douglas (dobro), Hall & Oates’ John Oates (vocals and guitar), Nick Forester (guitar), Pete Wernick (banjo) and Benny Galloway (vocals and guitar).

Bush and Douglas sat in the band for “Follow Me Down to The Riverside” and “Up On The Hill Where There Do The Boogie” before Oates joined the fray for “All That I Ask Of You,” “Crow Black Chicken” and “Had I Known Better.” Forester and Wernick were the next to make an appearance when they came out for “Polka On A Banjo” and “Pow Wow The Indian Boys” before Douglas and Bush returned to help them close out the first set with a “Come Together” that segued into “Little Maggie.”

Set two got going with “Blue Collar Blues,” while Douglas came back out for “Hey Bulldog.” Forester and Galloway then joined in for “Everytime” and “Poor House.” Next, Bush took the stage to help the band and Douglas with “We Hide And Seek” before Yonder departed for a few songs, giving Bush and Douglas a chance to play a “Crossroads” that was sandwiched between “Sailing Shoes” as a duo. Douglas, Bush, Oates, Forester and Wernick then took the stage with Yonder for a set-closing “Girlfriend Is Better” > “After Midnight” combo. The band and their guests then returned to the stage one last time for a extended encore of “Walking Shoes,” “One Love” and “Shady Grove.”
