From a Sheryl Crow concert a couple days ago in Virginia. One of her two encores is a cover of the Allman Brothers Band's "Midnight Rider". Sitting in with Sheryl is Lukas Nelson of the band Promise of the Real. Lukas is the son of Willie Nelson.
Both Crow and both father & son Nelson are part of Farm Aid at Key Bank Pavilion in Burgettstown this September.
In this clip, Audley Freed (formerly of the Black Crowes, now Sheryl's backing guitarist) plays along!
