Love me some Alison Krauss!  All day long, any day and everyday. I also love me some Led Zeppelin.  Mix them together and lookout!

One of my favorite shows was Country Crossroads on CMT.  There were some fantastic collaborations put together, but in my opinion, none were better than Alison Krauss with Robert Plant in 2008.

I do have to admit though that Brooks and Dunn with ZZ Top was pretty awesome too!

Anyhoo, check this out on a Friday Free For All...my all time favorite collaboration song.   These two absolutely nail the Zeppelin classic.
