In 1997, Sherlock allowed Jim Yoakum to start the 'Graham Chapman Archives'. Later that year, the novel "Graham Crackers: Fuzzy Memories, Silly Bits, and Outright Lies" was released. It is a semi-sequel to "A Liar's Autobiography", with Chapman's works compiled by Yoakum. A compendium of writings, "Calcium Made Interesting: Sketches, Letters, Essays & Gondolas", also compiled and edited by Yoakum, was published in 2005 in association with the David Sherlock and John Tomiczeck trust. In 2000, Chapman's play "O Happy Day" was performed by Dad's Garage Theatre Company in Atlanta, Georgia, with the assistance of Cleese and Palin. In 2006, the album and DVD release "Looks Like Another Brown Trouser Job" came out, featuring a college lecture recorded in April 1988.
