Good bunch comedy guests among the competitors this week as Alexander Armstrong and Richard Osman present as Nina Conti, Tim Vine, Denis Lawson, Rosie Marcel, Shazia Mirza, Sara Barron, John Pienaar and Joanna Gosling.

Look out for Sara Barron, the acidic American who is one of comedy's latest rising stars. Barron was nominated for a Best Newcomer Award in Edinburgh for her no holds barred sexually frank debut show For Worse, about growing up in America and moving to the UK. Barron has lived in London for a number of years now and is married to Radio DJ Geoff Lloyd,

Shazie Mirza has been around for a while but I recently enjoyed her latest live show, Coconut, at the Soho Theatre. You can read a review here. In In 2008 Mirza was listed in The Observer as one of the 50 funniest acts in British comedy, won 'Columnist of the Year’ at the prestigious PPA Awards for her fortnightly column in The New Statesman and won The GG2 Young Achiever of the Year Award. She has performed all over the world, selling out performances from Singapore to Kosovo, and regularly writes for various publications, including The Guardian, The Financial Times and New Internationalist.

Ventrolquist Nina Conti is on tour at the moment with her Dating Show in which she uses her particular set of skills to match up audience members for comic effect. Buy tickets her her live show here,

One-liner king Tim Vine is also touring at the moment, but not with a comedy show. His Plastic Elvis show is a genuine tribute to his hero Elvis Presley. The hero worship is real, only the quiff is fake. Vine says: "This isn’t a stand up show, but a concert dedicated to my favourite performer. When I was eleven years old, I would stand in front of my bedroom mirror and mime to the whole of 1972’s Elvis: As Recorded at Madison Square Garden album. This is a tribute act that is forty years in the making. Well, the waiting is over. It’s time to go public.”
