Russell Brand has been reunited on stage with Jonathan Ross and apologised again for their role in Sachsgate.
The comic said their antics were "not deliberately malicious but deliberately stupid".
The pair suffered a spectacular fall from grace when they left lewd messages on the answering machine of veteran actor Andrew Sachs - prompting a storm over their actions.
Brand resisted the temptation to sing part of the song they sang down the actor's phone at the time despite a request from the audience. He joked: "I'd better not do the Andrew Sachs song because as you know it nearly destroyed the earth."
He read extracts from his new book at the event at the Hackney Empire in east London before being joined on stage by Ross for a question and answer session.
At one point Brand waved what he said was a BBC compliance form, introduced by the Corporation after the scandal to regulate programme makers, which he claimed was signed by broadcaster Jeremy Paxman complete with the words "Russell this your fault".
He also discussed his relationship with his hero Morrissey and the start of his career in Hollywood.
Brand also talked about his new film, a remake of the Dudley Moore vehicle Arthur, which he said will be "a beautiful film".
But the memory of Sachsgate, which Ross dubbed the "elephant in the room", was never far away, with Brand joking he was "not very good at judging the time or right from wrong" when his performance threatened to overrun.
The performance was part of a promotional tour for Booky Wook 2 - the follow-up to Brand's first volume of memoirs.
