[Youdopia links have broken. A version of Youdopia is available on Tumblr here. Edit 10/2017]
I've updated, or udpated as I wrote the first time and I think I like better, the favorites link to Youdopia, as it is now back at its original site. It's the coolest site ever.
Youdopia has a post on Jimmy Page's recent foray back into live playing with Donovan last week. So, to save me the hassle of writing my own, here's their post. Yes, Jimmy reprised his session work on Donovan's Sunshine Superman live on stage. It was recorded in 1966, so it probably wasn't particularly challenging for Jimmy to play in 2011, but it's a start.
Videos of the gig at the link.
