Most Jethro Tull fans know that the group was named for the inventor of an agricultural implement, but few know much more than that about him. Ian Anderson will tell his story in a Rock Opera of sorts. Rather than approach the story in its historical context, Anderson will reveal it as a future occurrence. Tentative plans call for the production to debut in September in England before touring Russia, Europe and South America. A more conventional Tull project is also in the works. On May 4, an expanded edition of Minstrel In The Gallery will be released.
