Pop star, ex-Bond girl and model Grace Jones has agreed to star in an event which aims to break a world record for the largest "same surname" gathering.
Grace will join Joneses in styles ranging from opera to musicals
The Jones Jones Jones concert in Cardiff in November hopes to attract hundreds of Joneses on one night, on stage and in the audience.
Other Joneses involved include Blue Peter presenter Gethin Jones and opera singer Dame Gwyneth Jones.
The current Guinness World Record is held by 583 Norbergs in Sweden.
Organisers are confident they can comfortably beat the record, based on current ticket sales to Joneses and also invited guests.
Grace Jones, who found fame as a style diva, is expected to perform at the event being held at the city's Wales Millennium Centre.
The Jamaican-born singer became a 1980s club favourite with her seminal Slave to the Rhythm album, as well as her pop hit Pull Up to the Bumper.
She also starred opposite Roger Moore in the James Bond film A View To A Kill.
But Jones also recently topped a poll of most shocking chat show moments, for her appearence on the Russell Harty TV show 25 years ago, when she famously "slapped" the host when he turned his back on her.
Stifyn Parri, who runs the event management company involved in the production, said: "We have to say that Grace Jones has been nothing but a pussy cat".
He added: "She's going to blow your socks off! What a cherry for the Joneses cake."
A change of name for the famous inscription on the venue?
After being approached with the idea, Mr Parri said her agent came back immediately with the words: "Yes Grace thinks it is a fun idea."
Jones, known as much for her striking looks and style, has asked for a limousine and champagne in the hours before her first appearence in Wales.
Other well known Joneses taking part include from the world of opera, soprano Dame Gwyneth Jones and tenor Gwyn Hughes Jones, as well as West End performer John Owen-Jones.
Although Jones is one of the most common Welsh surnames, participants do not have to have a connection with Wales.
Presenter and singer Dai Jones who is also taking part said: "Grace Jones' singing style is very different to mine, but I really can't wait to see her perform.
"Dame Gwyneth's repertoire I know somewhat better, but these two famous names reflect the cross-section of Joneses who will give this evening an international flavour."
The concert is taking place on 3 November and will be broadcast on S4C on 26 November.
