AN internationally infamous drug smuggler-cum-author, an outrageous Aussie comic, and a former star of Never Mind the Buzzcocks are among the latest confirmed comedians for this year’s Sonisphere festival.

Howard Marks, whose autobiography Mr Nice is an international best seller, will deliver the Sunday Sermon at the Knebworth festival, which was given last year by hardcore hero Henry Rollins.

Mr Marks was an international drug dealer who, after a stretch in a US prison, went on to work with the British secret service , manage the Super Furry Animals and campaign vigorously for drug legalisation.

The youngest ever Perrier Award winner, Sean Hughes, returns to Sonisphere, held between July 8-10, to headline the comedy bill on the Bohemia stage.

His rapid fire wit has seen him star in Never Mind The Buzzcocks, The Last Detective and a guest stint in Coronation Street.

Despite a nine-year break in performing live comedy he was recently voted the 40th greatest stand-up in a Channel 4 poll.

Outspoken Australian cult comic Brendon Burns will also join the comedy line-up whose brutal comedic style should go down a treat with revellers.

Andrew Maxwell, Tiffany Stevenson, Nick Helm and Jim Smallman are also appearing.

Yesterday’s (Wednesday) announcment completes the Knebworth festival’s comedy line-up with the acts joining Bill Bailey, Metallica, Slayer and Slpiknot at Knebworth House between July 8-10.
