The show features 20 of their greatest songs, including “La vie en Rose”, “Milord”, and “Where Have All the Flowers Gone”.

Written by Daniel Boymann and Thomas Kahny, it’s been adapted by Erin Shields from the translation into English by Sam Madwar, based on a concept by David Winterberg. Gordon Greenberg directs, Jonathan Monro is the musical director, and Martin Ferland is the set designer.
