Recorded live in Nashville, this duet album finds the red-haired stranger making nice with artists as far flung as Sheryl Crow, Ryan Adams and Jon Bon Jovi. The one real highlight: Keith Richards' cameo on "Dead Flowers," where two grizzled sons-of-bitches take the Stones down a country road.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
