In 1916, following the Easter uprising, both moved to Liverpool, where, on the direction of a doctor, Kelly was registered in a dance class to strengthen her frail legs.

"Mistinguett later had them fired, but, undaunted, Kelly moved to the Paramount cinema [fr][2] (on the Boulevard des Capucines[3]) which with lavish cine-variety shows was trying to emulate New York's Radio City Music Hall.

"Les Blue Bell Paramount Girls" became the Parisian Rockettes, (dancing during the interval[4]) even appearing in a number of frothy film musicals.

As a full-time administrator and choreographer, Kelly installed her second troupe at the Folies Bergère, and imposed a minimum height of 5ft 9in (she was only 5ft 7in), recruiting them from Britain because she found British girls were better team players.

The French Resistance helped him flee from Gurs and return to Paris, where he was hidden by his wife opposite the Prefecture of Police building until the Liberation.

While beginning with a modest contract in 1947, the Bluebell Girls quickly became the sole stars of the Lido shows and gained notoriety locally and nationally.

From 1947, Marcel Leibovici had entered in full partnership with his wife, managing the orchestral, business and financial side of her operation and, thanks to his considerable flair, had made the Bluebell Girls one of the most celebrated and prestigious dancing troupes in the world.

[5] Margaret now became wholly responsible for their four children: Patrick, Francis, Florence and Jean-Paul, and kept the Bluebell's programme in steady operation, even increasing the number of troupes and activities by continually adding innovative new elements and artists.

[5] In 1986 Kelly went into semi-retirement and left the Paris Lido, but she continued her global activities, particularly in Las Vegas with the MGM Grand Hotel.

[citation needed] In 1986 the BBC broadcast a major drama series called Bluebell[14] produced by Richard Bates and George Perry who wrote her authorized biography.

On June 24, 2010, Bluebell Girls belonging to four generations and coming from around the world celebrated the first centenary of the birth of Kelly by meeting at the Lido de Paris.

[citation needed] Within the framework of its mission to present the history of entertainment, the University of Nevada in Las Vegas (UNLV) is paying a permanent tribute to Miss Bluebell by showing photographs of her in its on-line exhibit of photos SHOWGIRLS and in the famous Donn Arden Special Collection, thus reuniting for ever the two partners who played such a signature role in the history of show business and contributed so much to the legend of the Bluebell Girls.
