It is the age of the Pre-Raphaelite Brotherhood, when Europe burns with a passio
n for long, flowing locks. And when seven Irish sisters, penniless and fatherles
s, grow up with hair cascading down their backs, to their ankles, and beyond, me
n are not slow to recognise their potential. It begins with a singing and dancin
g septet, but this is not what fills the seats: it is the torrents of hair they
let loose at the end of each show.
