My TiVo just picked this up last night... it's quite excellent so you may want to check your local PBS station to see if it replays. And it even ties in to Arlo since he's performed with Emmylou before. Now, wonder what Mark & Arlo would sound like together - that would be an interesting combination. For those who may be unaware, Mark Knopfler is/was the lead singer and guitarist for Dire Straits (Sultans of Swing, I Want My MTV). This show was just an absolute delight!

From the PBS site:

"A great venue, a great tour, two great artists and a great performance. So it was for icons Mark Knopfler and Emmylou Harris at the Gibson Amphitheatre in Los Angeles before a sold-out crowd. Their concert together, one of only a handful in the U.S., followed the release of All the Roadrunning, their long-awaited rootsy collaboration. That special night has been captured in this unique Soundstage episode. Highlights include the title track “All the Roadrunning,” Emmylou’s “Red Dirt Girl” and Knopfler’s “Speedway at Nazareth.”"
