Dierks’s wife Cassidy tells, “The bluegrass band at the Station Inn accompanied them, and Evie sang ‘Let It Go’ — from Frozen, which has completely taken over our life — and then Jordan did ‘Twinkle, Twinkle, Little Star.'”

Kacey Musgraves also joined Dierks for a performance of Buck Owens‘ “Act Naturally.”  Kip Moore was spotted in the audience, too.
