Spoof DJs Smashey and Nicey are making a comeback for BBC Radio 2's 40th anniversary celebrations.
Smashey and Nicey were popular comic creations of the 1990s
The comic characters - played by Paul Whitehouse and Harry Enfield - will present a special edition of Pick of The Pops on 30 September.
The show, which was hosted by late DJ Alan "Fluff" Freeman, will feature a chart rundown from 40 years ago.
Listeners are also being asked to vote for their ultimate icon from popular culture over the last four decades.
The winner will be announced during the day's special programming to mark the station's 40th birthday on 30 September.
Paul Hollingdale, who was the first voice on the network in 1967, will present the breakfast show, while veteran broadcaster Michael Aspel returns to the station with an edition of request show Family Favourites.

Radio 2 controller Lesley Douglas said: "I am thrilled that Harry Enfield and Paul Whitehouse have agreed to bring back Smashey and Nicey for a one off Pick Of The Pops special.
"To welcome back some of the stars from the original line-up, to re-live some of the musical and comic gems is really exciting.
"This special day will give listeners old and new a chance to sample some of the gems of the past 40 years," she added.
Pick of the Pops' top 10 from 40 years ago will feature songs from Cliff Richard and The Flowerpot Men, culminating in chart-topper The Last Waltz from Engelbert Humperdinck.
The comic pair, Mike Smash and Dave Nice, were regular characters on Harry Enfield's sketch shows during the 1990s. A 1994 TV special featured them being sacked from their radio job.
