It is presumably a source of great satisfaction to Adam Hills, Alex Brooker and Josh Widdicombe that this chatshow - which began with a focus on disability issues - has completely transcended its original brief to become a sparky and engaging Friday night fixture with universal appeal. But tonight, it's back on its original beat, welcoming Ellie Simmonds, Jonnie Peacock and Liam Malone to discuss the World Para Athletics Championships in London.

Alongside footballer Rio Ferdinand and Coronation Street star Michelle Keegan will be Paralympics champion Jonnie Peacock, TV and radio host Sara Cox and comedian Josh Widdicombe. Stephen Merchant hosts.

Further Paralympics roundup fun from Adam Hills, Alex Brooker and Josh Widdicombe. Day three sees wheelchair sprinter "Hurricane" Hannah Cockcroft start the defence of her two 2012 gold medals by competing in the T34 100m, as well as medal hopes in swimming, shooting and judo. Commenting on all that and other news from the Games are powerlifter Ali Jawad, sprinter Jonnie Peacock and comic actor Stephen Mangan.

It's the motor-mouthed host's last show this year and a bumper cast squeezes onto his banquette of banter for the occasion. Ross welcomes arena-filling stand-up Michael McIntyre, actresses Sheridan Smith and Sienna Miller, plus Paralympic gold medallists Ellie Simmonds and Jonnie Peacock. Chef Jamie Oliver cooks festive food, while there's music from Charlotte Church and clowning from Broadway-wowing Russian troupe Slava's Snow Show.
