In 2007 Josephine was introduced to Alain Boublil, who together with Claude-Michel Schonberg, wrote the phenomenally successful musical 'Les Miserables'. Their association led to her producing two concerts for his wife, the soprano Marie Zamora, one in the elegant surroundings at Leighton House Museum in Holland park, and the other at the prestigious Joe's Pub in New York.

Her association with Alain and Claude-Michel continued when Josephine produced the three week workshop presentation of their collaboration with Michel LeGrand, 'Margeurite', which went on to open at The Haymarket in 2008.

Josephine's second project in New York was a concert by the soprano, Claire Moore ('Phantom of the Opera', 'Miss Saigon', 'The King and I'), at The Weill, one of the three concert halls at Carnegie. This was a musical collaboration between Claire and her husband, the composer and arranger, Simon Hale (Jamiroquai, 'Spring Awakening').
