Eat your heart out Florez and Dessay.  A new pair of principals have hit London and star in Laurent Pelly’s 12 year old production of La Fille du regiment.  The mishmash production is very much a ‘Dad’s Army’ fun billing.  The comedy is always at the forefront and is infectious and the two new principals bring the house down.  In fact there appears no singing weak link in a most enjoyable evening.
