This is incorrectly labeled as The Nitty Gritty Dirt Band, but it's The Byrds covering Dylan's "You Ain't Going Nowhere"
Actually, it's Roger McGuinn of the Byrds in a duet with the Nitty Gritty Dirt Band.
From songfacts
Roger McGuinn of The Byrds buggered a line, transposing the words "pack" and "pick"...so, on a rerecording of the song for GREATEST HITS 2, Dylan sort of calls him out: "Pack up your money, pick up your tent, McGuinn--you ain't goin' nowhere!". All in good fun, of course...
McGuinn returns the favor in a late '80s version he and Chris Hillman cut with the Nitty Gritty Dirt Band for their "Will the Circle Be Unbroken." McGuinn sings, "pack up your money pull up your tent, Dyl-an, you ain't a goin' nowhere."
It may be Dylan's song, but McGuinn does it best, and continues to perform it to this day in his solo acoustic shows.
