It's been years since BFF comics Jon Richardson, Lloyd Langford and Dan Atkinson teamed up for their three-hander, 'Git'. (Well, it's been yonks since they performed it in London, at least.)
'Git's largely improvised, with the three of them ripping the piss out of each other, messing about with Photoshop and taking on silly challenges. Oh, and probably drinking quite heavily. It's a lot of fun.
