Howard Marks is among the latest names to sign up for Sonisphere 2011, held from 8-10 July at Knebworth.
The reformed smuggler and prolific author is set to take the Sunday Sermon, which last year was hosted by Henry Rollins.
Sean Hughes, Andrew Maxwell and Brendon Burns are set to perform their comedy routines, with Tiffany Stevenson, Nick Helm and Jim Smallman joining them on the Bohemia Stage.
They join the Big Four (Metallica, Slayer, Megadeth and Anthrax), as well as Slipknot, Biffy Clyro and fellow comedian Bill Bailey on the line-up for the three day festival.
Guest ticket holders get to camp in the exclusive guest camping site with separate loos, and to access the hospitality bar, where the festival’s music industry guests rub shoulders.
All you have to do to be in with a chance of winning one of two pairs of Guest upgrades is buy your tickets through the VF ticket link below.
Winners will be chosen at random and informed on Friday 24th June.
