I guess the "News" section on P&T.com should be updated a bit more frequently...
I got this in a ticketline newsletter a few days ago:
Penn & Teller
35 Years of Magic & BS!
Comic Magicians, or 'Evil Geniuses' as described by David Letterman, Penn & Teller will be returning to the UK this winter to play 2 very special nights at London's Indigo at The O2 on December 7th and 8th.
Conversations with Penn & Teller: 35 Years of Magic & BS! is an insightful evening of candid discussion, audience Q&A, video clips and some of Penn & Teller's classic magic tricks performed live.
