Lou Stein's adaptation of "Fear and Loathing in Las Vegas" was performed at the Battersea theatre. Stein persuades London's 'Time Out' Magazine to put Thompson up for a fortnight, in exchange for him writing a cover story to publicize the play. Thompson doesn't write the story, but does rampage around London on Time Out's expense account. The play was revived for the Vault Fringe Festival in 2014. GONZO: A Brutal Chrysalis is a one-man show about Thompson written by Paul Addis, who also played the author. Set in the writing den of Thompson's Woody Creek home, the show portrays his life between 1968 and 1971. James Cartee began playing the role soon after Addis's arrest in 2009, and again after Addis's death in 2012.
Question: How many years passed between Addis's death and the revival of the play "Fear and Loathing in Las Vegas" for the Vault Fringe Festival?
Answer: 2
