He always stood out amongst the crowd and he had this black, wavy hair – he looked a bit like him!’He stole the show, singing all the songs. I think the girls were swooning over him.’Reacting to his Emmy success, Delyth said: ‘I saw the news this morning and it didn’t surprise me at all. We’re all so proud of Matthew.’For the Elvis production, his teacher said he watched videos for hours until he had memorised all of the mannerisms.Delyth said: ‘He was so enthusiastic about everything. If he was doing something, he would give it 100 per cent.’Costume designer Julie Morse created the spectacular outfits, while Matthew’s mother and father watched him perform every night.

He had this twinkle in his eye.’He lived life to the full and he was very humorous. His sense of humour is so dry and he’s so funny.’He was a very popular lad, but so unassuming. He had something very unique.’ Delyth hugging Matthew after watching him perform last year But more than three decades before conquering Hollywood, he was swivelling his hips in a gold suit at Welsh-language school Ysgol Gyfun Gymraeg Glantaf in CardiffReacting to his Emmy triumph, Delyth said: ‘When I saw The Beast in Me, I was so in awe of all his talents.
