Vic Reeves and Bob Mortimer's one-off special of "Big Night Out" will air over Christmas.
The popular duo announced earlier this year that they were working on a lone episode of the cult comedy series, which ran for just 15 episodes on Channel 4 from 1990 until 1991 and made them household names, and now it has been confirmed that it will air on BBC2 on December 29.
Taking to his Twitter account, Bob, 58, said: "ALL NEW VIC AND BOBS BIG NIGHT OUT
"Dec 29th 9:00pm BBC2#terrific (sic)"
The new show, which will be a "re-imagining" of the original, will feature new characters, cameo appearances, songs, skits and stunts performed in front of a live studio audience.
The pair - whose show was based on their stand-up gigs at Goldsmiths Tavern in South London - said in a statement earlier this year: "This is the show we wanted to perform back in the 1980s. Now the time is right. We will be increasing our respective heights in order to perform some of the more intricate and challenging moments."
Shane Allen, the BBC's controller of comedy commissioning, added: "In this special, Vic and Bob go back to their live stage show roots to mark three decades as the most pioneering, surreal and unique pairing in British comedy.
"With a mix of old and new characters, recorded in an intimate setting they give a modern spin on that rich tradition of English eccentricity that stretches back to the music hall, through Spike Milligan and The Pythons in creating characters that delight or baffle depending on who you are."
The news that they were working on a one-off special initially came as a surprise to fans as the pair teased they were working on a "low-quality" show for the BBC that would be like "nothing" they've ever done before.
Vic - whose real name is Jim Moir - said at the time: "We're writing a sketch show for the BBC, it's going to be absolutely brand new, nothing has ever been done like this before.
"It's done on the cheap. Really cheap. And also on the hoof. It's about really low-quality filming and low-quality comedy."
