The half-hour special, which is due to be broadcast on Sunday 27th June, has been created by David Spicer. The writer has previously worked on Radio 4 sitcoms such as Polyoaks and Double Income, No Kids Yet.
Radio 4 explains: "Bill plays Guy Starling, a middle aged man who, after 45 years, suddenly meets up with his imaginary childhood friend, Hennikay. It's the biggest day in his career and he is on the brink of closing the biggest deal yet but, when Guy strides into his office at Solutify Technology, a software house that develops games for grown-ups to spend their time playing on their phones, he is confronted with an 11 year old boy playing keepy-uppies. And to make matters worse, no one else can see or hear him because he is Hennikay, Guy's imaginary friend from his lonely childhood."
The special will also star Sanjeev Bhaskar as Tony, Elizabeth Carling as Marika, Anna Leong Brophy as Kallie and John Schwab as Don, with Max Pattison - who plays Benji in Not Going Out - voicing the role of Hennikay.
Sioned Wiliam, Radio 4's commissioning editor for comedy, adds: "It's wonderful having Bill back on Radio 4, acting in this touching and witty script. The role suits him down to the ground, making the most of his brilliant comic timing and charismatic presence."
