Mamma Mia marks only the second major musical theatre production Jeffares has been involved with, although she has enjoyed being on stage since she was a child. A regular singing performer in the Napier Easter competitions, she was singled out by a teacher when she was six, who suggested to her parents that she have vocal lessons.
One of her early mentors, who became a good friend, was singing teacher, the late Frances Burch.
Last year Jeffares was understudy to Daniela-Rose Cepeda, who played Christine in Napier Operatic's Phantom of the Opera. "It was the first big show I'd ever done and it gave me a good understanding of being on stage. To be understudy as well was a real confidence booster, I had such great support and mentoring from [director] Gillian Davies and Daniela."
She hopes audiences take the time to think about the relationships, and ideas of relationships that inform the show. Yes, Abba's timeless tunes are catchy, but there's more to Mamma Mia than just songs, she says.
Sophie is getting married because she thinks that's the right thing to do. "You see the whole dynamic between Sophie and Donna. Because I am a mother myself I can imagine the scenario well, the whole idea about the lifelong bond. That song Slipping Through my Fingers, it's my favourite out of the whole show."
