Anagramical!

High priestess of Gallic Druids, visually masquerading as Catalonian Catholics, I get the feeling her oath of chastity was blown by her two kids from someone hunky but totally unsuitable. She'd shagged the Roman enemy... not once but at least twice. She was pretty tasty so it's odd her Roman candle fizzled out as he dumped her for her underling.

What about the kids? Well she was going to murder them but just stopped herself. It ended well when Norma and her anagram climbed on the pyre.

Spectacular music, spectacular set.

Norma drained me, putting the belle in 'bel canto'.
