The Welsh rock trio kick off their UK tour in early August.
England head coach Eddie Jones will lead the Barbarians team when they face Fiji later this year.
The two teams will face off in a one off match at Twickenham Stadium on Saturday 16 November 2019.
The game will be the first international rugby match staged in the UK following the 2019 Rugby World Cup.
The upcoming Rugby World Cup kicks off in Japan this September, and Jones will be hoping to coach his England team to their first victory in the tournament since 2003, when England captain Johnny Wilkinson lead the team to glory in Australia.
The match will mark the first time the coach has taken charge of the Barbarians, who are affectionately known as the Baa-Baas.
Jones comments: “It’s a huge honour to be invited to coach the Barbarians. The club perfectly embodies the values and traditions of the sport and fans can expect to see an exciting match between two sides who like to play end-to-end running rugby.”
During a 25 year long career, Jones has coached some of the game’s greatest ever players in some of the sport’s biggest occasions. Career highlights include coaching Australia to the 2003 World Cup final and leading England to their first Six Nations Grand Slam title for 13 years in 2016.
Taking place just two weeks after the upcoming Rugby World Cup final, a bumper crowd is expected at Twickenham to take in Barbarians against Fiji.
The last time the two sides met at Twickenham was in November 2013, where over 68,000 fans witnessed the Barbarians defeating Fiji 43-19.
Fans can expect Jones to lead a team featuring a number of players who will have competed in the 2019 Rugby World Cup.
