Six performers and a band, they all get to sing a couple of showcase songs and there are a few grandstanding ensemble pieces: the formula for Six is a pretty simple one. But my god it works.
The musical - themed around Henry VIII's wives but you probably already knew that - is just fun. Watching the cast have a ball on stage is infectious - and a bit like if you crossed Horrible Histories with a really good, 21st century hen party.
The all female cast and band bring energy, wit and some stellar vocal cords, and on Tuesday night the audience at Newcastle's Theatre Royal loved it. The show is zippy, running for not much more than an hour, and the genre hopping tracklist has something for everyone.
