That campaign also featured a defeat to Brazil, the side Scotland face later.
The parallels have not been lost on Ewen.
Scotland were beaten by Morocco on 23 June in 1998, and again last weekend.
But with Brazil next up, Ewen hopes this Scotland side can succeed where their predecessors fell short and finally change the script.
“It could be one of the best days of my life. I just can’t wait,” he said.
“It’s my birthday. On my 16th birthday, I watched Scotland lose 3-0 to Morocco and get put out.
“I’d love to see Scotland win at a World Cup. It would make my birthday and all my dreams come true.”
