Matilda, whose first single Invisible is out on March 21. MATILDA MacIntyre loves to sing and dance . Her auntie IS Clare Grogan, after all, and her parents are well-known Scottish musicians Katy Lironi and Douglas MacIntyre, so it is no huge surprise she fell in love with performing. But on holiday in Italy in 2015, the Lanarkshire schoolgirl discovered songwriting for the first time. The result is Invisible, her debut single, which will be released on World Down’s Syndrome Day on March 21. Matilda, 17, who has Down’s Syndrome, says: “I feel happy about my song. I really like the words.” Katy, of The Secret Goldfish and The Fizzbombs, explains: “Matilda wrote the song while we were on holiday and we haven’t been able to return since then. She wanted to record it to remind her of happier times and to celebrate WDSD.”
