Blind Audition Song: I Wish I Knew How It Feels to Be Free - Nina Simone
About: Based in Naas, this rather glamorous dental nurse likes to take care of all her facial features, not just the toothy bits. "Mascara is a girl's best friend," she says coyly. "Ideal for lovely long lashes." When she's not tinkering with people's cavities or yanking at her client's gobs, Niamh likes to sing the blues in her own inimitable style. Despite her claim to bona fide musician status, this singer has let it be known that her first ever record purchase was Kylie's ultra-pop ditty "I Should Be So Lucky". Chequered past, indeed.
