Last year, Harlequins man Kerr watched on like the rest of us as Ireland got the better of England 36-24 in Cork in March to complete their U20 Six Nations Grand Slam.
The two old rivals then met three months later in June in Paarl, South Africa, in the pool stage of the Junior World Trophy.
That game ended in an amazing 34-34 draw and it has left supporters keen for more.
Well, they do not have to wait any longer because on Friday evening the sides will meet in Round 4 of U20 Six Nations action at Bath’s Rec Ground with both teams currently unbeaten.
England have 15 points from a possible 15 thanks to bonus point wins over Italy, Wales and Scotland and top the standings – and will win the title with a bonus-point win.
Ireland have 14 points after wins over France, Italy and Wales and are second.
Ahead of this one, Kerr, the 19-year-old who starts at 12 for England, said: “These are the types of matches and occasions that every player wants to be involved in.
“This is my first season with the U20 squad and I am loving it so far.
“The environment in camp is great, all of the boys are getting on really well and we have clicked well on and off the pitch.
“I started the first game against Italy, but I hurt my ankle within the first 10 minutes and was hobbling around a bit until half-time.
“Unfortunately, I could not run the issue off, so I came off before missing the Wales game, but it was great to be back and starting versus Scotland in Round 3.
“It was quite hard watching from the sidelines against Wales, so I was really chuffed to be back involved up in Edinburgh and I felt like I played well and the team also did a good job, so we were happy.
“We have 15 points from 15 and are top of the table, the boys are happy with how things have come together and how we are playing, but we know that Ireland will be the toughest test we have faced yet.
“We have had a couple of things to work on this week and we are ready for a physical test.
“Having watched the Wales game from the stands, the atmosphere at the Rec was brilliant and I can only imagine how loud it will be this Friday - that will spur the boys on for sure.”
Kerr said that he felt like he played well in the 30- 17 win a fortnight ago against Scotland and others obviously felt so too because he was named player of the match after bagging a try, two penalties and two conversions.
Friday will be his third U20 cap and his rugby journey began at his local club Effingham and Leatherhead RFC in Surrey when he was five.
“We started with tag rugby and then, at the club and through school, I started to play contact rugby when I got a bit older and I just fell in love with the game,” Kerr explained.
“I have played it ever since and being involved with Harlequins age-grade and academy sides in recent years has really helped my development as has representative rugby and a stint at Richmond earlier this season.
“Playing senior rugby there helped me learn a lot about game management at a senior level while I made my full debut for Harlequins [in the Premiership Rugby Cup versus Nottingham in October] so now I just want to keep learning and play in big games like this Ireland one.”
The England-Ireland match on Friday kicks-off at 7.15pm.
