The 2012 edition of the Sunflower Jam will be held at the Royal Albert Hall in London on Sunday, September 16. Apparently Jon Lord’s treatment is proceeding well enough that he is billed to appear there. (And with the whole thing being organized by his sister-in-law, this must come from pretty close to home, so the news are really encouraging).
Other people confirmed so far include Ian Paice, Bruce Dickinson, violinist Nigel Kennedy, and opera singer Alfie Boe. Tickets priced £30 – £130 (plus booking fee) will go on sale through Eventim and the RAH box office soon.
Thanks to Planet Mosh for the info.
