Yes, I saw it. It was 2008 though so more than a couple of years ago! I found the production a mixture of shocking, enjoyable & cringeworthy at various points. Mind you, Candide's a guilty pleasure musical for me anyway. I tend to enjoy it while feeling I should be disapproving of it - and it's inevitably the most inappropriate lyrics that get stuck in my head afterwards!
It would be nice if the Menier could get opera singers for Candide & Cunegonde at least, though I'm not sure they will. As well as Pangloss, I don't think the Old Lady needs an opera singer either. Beverley Klein did the role both at ENO & in a concert performace I saw last year & she was fabulous despite not being at all operatic. That was the first, and probably the last, concert in which I've seen anyone vamping several younger men whilst standing on a chair!
