Only two players in either England or Wales' squads at Euro 2016 were alive the last time The Dragons got the better of the Three Lions.
Wales' David Vaughan and James Collins were both barely a year old when a sprightly Mark Hughes scored a match-winning goal on his international debut in February 1984 in the final British Home Championship.
England have won the four matches the two nations have played since, giving them a 65 per cent win ratio against Wales ahead of their crunch Group B clash in Lens tomorrow.
In 101 meetings, England have 66 wins to Wales' 14, with 21 draws between the pair.
You have to go back to pre-war Britain to find the last time Wales could have laid reasonable claim to being the dominant team of the UK rivalry, when they winning four and drew one of the nine meetings between the sides in the 1930s.
They've won just four meetings in the 78 years since.
A Welsh "golden generation" in the 1950s featuring John Charles, Ivor Allchurch and Cliff Jones only ever managed one win over England, although they did play in the 1958 World Cup — the last Welsh team to make a major international tournament until Chris Coleman's current crop.
Wales have 11 players in their Euro 2016 squad who were named in the matchday squad the last time they faced England, under Gary Speed at Wembley in 2011; Wayne Hennessey, Chris Gunter, Ashley Williams, Neil Taylor, Gareth Bale, Andy King, Aaron Ramsey, Joe Ledley, James Collins, Joe Allen and Hal Robson-Kanu.
England, meanwhile, have just Joe Hart, Chris Smalling, Gary Cahill, James Milner and Wayne Rooney remaining from the 1-0 win which put them on the verge of Euro 2012 qualification.
Their next game will mark the first time the two sides have ever met at a major tournament.
A famous 2-0 victory over Scotland 20 years ago marks the only other time an England side has met a home nations team at a major tournament, while England have played the Republic of Ireland twice; a 1-1 draw in the group stages of 1990 World Cup and a 1-0 loss at the European Championship two years earlier.
