"A special mention must go to the singer [Gráinne Gillis] who took over the role of Suzuki at very short notice, so short she had to perform holding a tablet with the score. She did a remarkable job despite the circumstances - her flower duet with Bork was delicate and harmonious..." - Manuel Munoz (A Younger Theatre) on "Madama Butterfly" with Secret Opera, 2016.


"....Gillis - whose voice has rich, dramatic potential - [is] powerful in the title role." - Fiona Maddocks (The Observer) on "The Medium", Grimeborn 2014.

'I was extremely lucky to be able to book Grainne to sing at my wedding recently and it was easily one of the highlights of the day. Grainne is not only supremely talented but a total professional. I'm not very knowledgeable about opera and Grainne was nothing but
delighted to sing some of my rather random song requests and also gave us some much appreciated guidance on song choices. It really added a captivating sparkle to the occasion and I cannot recommend her highly enough' - Annika Eade, Hackney Editor, Mumsnet
