Ryan Brierley suffered an ankle injury ahead of the game, which meant Addy was drafted into the number seven shirt, partnering Danny Brough in the halves.
Although the Scots lost 38 – 12, they made a fine start to the game, and made sure that England were pushed hard all the way.
“It’s always a proud moment playing in games like this,” Addy told Love Rugby League.
“I’ve got a lot of experience at halfback at club level, so it wasn’t a surprise, it wasn’t like I was chucked in at the deep end.
“We’ve had a real good week, and had plenty of time to prepare, and I think we pushed them close in that game.
“Obviously we’ve mentioned how good England are, and the other two teams in this comp.
“We started poorly last week, and to bounce back and start like we did this week, scoring first, it put us in a real arm wrestle, and we just dropped off back of that second half.
“There was a 20 minute spell in the second half where we were sloppy, but we managed to get a foot back in the game.
“I really enjoyed it.”
A key moment in the game came just before the match entered its final quarter, when Brough received a yellow card that many felt was harsh.
“I never like to bring refs into it,” Addy said.
“But there was one in the first half where Broughy made a break and got held down, which was very similar, and could have gone either way.”
