The station will broadcast a fourth series of the sketch showcase series, now to be hosted by actor, writer and musical comic Isy Suttie.
Suttie said today: "I'm very excited to be hosting the new series of Sketchorama, following in the footsteps of two sketch veterans in Humphrey Ker and Thom Tuck. It'll be like you're watching a great sketch show live. Except you'll be in your living room, eating blancmange, in a onesie. Everybody wins."
Previous hosts Humphrey Ker (Series 1) and Thom Tuck (Series 2 & 3), who comprise two thirds of The Penny Dreadfuls, will appear with fellow Dreadful David Reed as one of the guest acts to feature in the series.
The series will run for four episodes, to be recorded in London in June and in Edinburgh during August's Festival Fringe. To apply to be in a London audience see our free tickets page
The other acts confirmed to be performing during the London-recorded episodes are:
In Cahoots are an up and coming sketch duo formed of Paul G Raymond and Luke Manning. They are performing at this year's Fringe at the Pleasance Courtyard after two well received shows on the Free Fringe.
Hennessy & Friends
Miranda Hennessy, David Seymour and Steven Shapland won 'So you think that's funny? Best new sketch act 2014'. The trio met at Drama School and formed in 2012. They have taken two sell-out shows to the Edinburgh Festival, garnering a host of four and five star reviews in the process.
Frisky & Mannish
Sketch comedy filled to the brim with Glenn Moore and Matt Stevens. They formed in Sheffield in 2011 and made their full Edinburgh Fringe debut in 2013. 'Without question one of the funniest sketch shows on the Fringe' - GQ
Lazy Susan are writer-performers Celeste Dring and Freya Parker. They became one of the buzz shows of the Edinburgh Festival Fringe in 2014, earning a Foster's Edinburgh Comedy Award Best Newcomer nomination.
The Twins Macabre are a deliciously dark character-comedy duo made up of Nicola Lamont & Adam Rhys Davies. Ivy and Maurice Macabre are infamous psychic siblings who conjure souls of the damned through twisted sketches and songs.
Gein's Family Giftshop
Gein's Family Giftshop is comprised of Kath Hughes, James Meehan, Kiri Pritchard-McLean and Edward Easton. The quartet joined forces in the city of Salford post University and have been arguing on long car journey's ever since.

The series returns on Wednesday 5th August on Radio 4.
