Robert Plant joined collaborator and romantic partner Patty Griffin onstage at the tiny Continental Club in Austin, Texas on Saturday night for a set that included reworked versions of a number of Led Zeppelin classics. 

The couple went through several more of Griffin's own songs as well as Zeppelin chestnuts like "Black Country Woman," "What Is And What Should Never Be," "Tangerine," "Going To California" and "Black Dog."

Check out "Black Dog"

 

Interesting version.

K.C.-ya!
