Lewis, 20, feared he was heading nowhere fast at the start of the season when Norwich made it clear they did not see much of a future for him at Carrow Road.
He recalled: "I was in the reserves at Norwich but nobody really wanted me there and I never played a first-team game for them.
"But I needed first-team football and figured if the team was under pressure it was a chance for the keeper to be the star.
"I was desperate to move so I took Morecambe's offer and luckily it worked out.
"Suddenly I was up against big, ugly League Two strikers. I got a few knocks, but it was good fun. While I was there I had a couple of good games against Peterborough, who made Norwich an offer for me in January and that was it.
"We won promotion to League One and I was called into the England Under-21s against Wales in May."
Yet even when Chris Kirkland pulled out with a back injury Lewis still never imagined he would be promoted to the senior squad for tomorrow's friendly against Trinidad.
He admitted: "I got a call from the FA at six o'clock and two hours later was on my way to the hotel.
"I just grabbed a bag and went. I was due to go to Mexico with my mates but it's a small price to pay."
