The lead singer of T-Pau, who grew up in Wellington and Shrewsbury, was a contestant on a music edition of BBC1's Pointless Celebrities.
The China in Your Hand singer paired up with Limahl, former frontman of Kajagoogoo. The other star pairs playing were punk singer Toyah Willcox and Mark King, singer and bass player in Level 42.
Slade guitarist Dave Hill and Showaddywaddy's Dave Bartram and boy band stars Antony Costa from Blue and Scott Robinson from 5ive also took part.
Between them, the star line up had sold 40 million records worldwide and had top 10 hits across five decades.
The episode of the popular quiz show hosted by Alexander Armstrong and Richard Osman was aired on Saturday night.
Alexander asked Carol: "T'Pau – what's that mean?"
The flame-haired frontwoman replied: "T'Pau was a character in the original Star Trek series and she was Mr Spock's paternal grandmother. She sat on the intergalactic council. But I'm not a Trekkie anorak or anything. But we could have been called Klingon so I think I made the right choice."
Alexander asked Carol what she was up to at the moment and she replied: "Touring, gigging, just never stop doing the live work at all. Everybody just loves the Eighties."
Carol got off to a good start in the quiz, winning the first question on nations of the 2014 Winter Olympics after guessing 25-pointer Jamaica.
And staying strong, Carol and Limahl got to the head to head against the two Daves.
They won the game on 1980s TV theme tunes after guessing Lovejoy for10 points against the Daves 74 for Eastenders.
But wrongly identifying Alex James from Blur as Dougie Poynter from McFly in the men in skirts round saw them knocked out.
The pair would have been through to the final if they had gone with their other answer of Jean Paul Gautier which was worth 14 points. Hill and Bartram reached the final and won the jackpot. They took home £2,750 for Silver Star Diabetes Awareness and Lord's Taverners Charity.
