I tthought the best part, other than the "In My Time of Dying" solos which stole the show, was Edge mentioning to Jack, "There's a bit of punk in this man," referring to Jimmy Page.
I concur!
And by the way, I think Jack White is brilliant. Others that think so: Stones and Scorcese (see Shine a Light); Beck; Loretta Lynn; The Edge; pretty much any musical genre artist, and oh, about about a 22 million others...
Listen to his piano on "You Don't Understand Me" by Raconteurs. Yes, he has skills.
