Mark Knopfler & James Taylor

+1 for American Tune. I particularly like the Willie Nelson/Paul Simon duet on Willie's "Across the Borderline", a great album which also includes a duet with Dylan on Heartland.

But if you want something that "gets you" every time, there's nothing like the Playing for Change video series that can be found on YouTube. If you haven't seen them, each video blends clips of local musicians from around the world, many of them who are street musicians, playing a song often featuring a well known artist. Here are some of my favorites (but they're all terrific):

Gimme Shelter (Taj Mahal) 

Teach Your Children (Tula Ben Ari - female singer from Israel with a great voice and vocal style)

Ripple (Bill Kreutzmann, David Crosby, Jimmy Buffet, David Hidalgo)

The Weight (Ringo Starr & Robbie Robertson)

Listen to the Music (Tom Johnston) - Outstanding!!

Guantanamera

Stand by Me

Higher Ground

Get Up, Stand Up (Keith Richards & Keb Mo)

Seasons in the Sun by Terry Jacks

One of those rare songs that moves me every time I hear it.

Jacques Brel and Rod McKuen wrote "Seasons in the Sun" and Terry Jacks performed a shortened version of that song.  The original is a bit creepy because the dead narrator, in the last verse, tells his wife he knows she had been cheating on him and that he intends to haunt her in death.

I like another cover of the song by a British group called Black Box Recorder.

I'll play! In no particular order...

Santana - Oy Como Va

Vivaldi - Spring (Four Seasons) 

Strauss - Blue Danube Waltz

Steely Dan - Time Out of Mind

Doors - L.A. Woman

James Taylor - Mexico

Allman Brothers - In Memory of Elizabeth Reed

Pink Floyd - Comfortably Numb

Miles Davis - Flamenco Sketches

Dave Brubeck - Take Five

David Sancious and Tone - Move On

Doobie Brothers - Takin' It to the Streets

Breaking Benjamin - Blow Me Away

Happy listening.
