I expect Joe is rehearsing for the Teen Cancer America - Celebration of The Who show (Rosemont Theatre Chicago on the 14th May).
I don't know if this is related to that show but Grizzly Bear singer Edward Droste has been jamming with Joe.
https://twitter.com/edwarddrosteJust got to sing alongside both my dear @thevandykeparks but also Joe Walsh from the Eagles ☺️😳☺️🎉 (such a great experience! )
The Who show looks a good-un. Joe's often spoken highly of jamming with Townshend over the decades. It'll be a rare treat to see them playing on stage together.
An Evening Celebrating The Who with Pete Townshend, Eddie Vedder & Friends.

The evening will be hosted by Roger Daltrey.
