Colback was a second-half substitute in the famous 3-0 triumph.
"I was getting quite a lot of stick warming up - you'll not need to ask why - so it as good to get the last laugh," he told The Journal.
"To be fair, there were a couple of Newcastle fans who had been giving me a bit of stick, but they clapped me off. So give them their due, although 99 per cent were still effing and blinding.
"It was a great day for the team, the staff, the manager and obviously the fans. They've finally got the chance to give some stick back and I'm sure they've been doing that."
