This may be the one Dominic is talking about? Johnny B. Goode, Live, From Brazil! (I haven't heard it. Kid next to me is watching cartoons. But I will take a look later.) See lots more on www.chuckberry.com/forum.
(8 hours later, and I've listened. It sounds kind of like an extended, off key version of "Concerto in B Goode." But everyone is clearly having a good time, so who cares? A modern Chuck Berry concert is a celebration of what is, was, and always shall be-- which I think is cathechism.)
