British imports also had success at the Tony awards
Musical production South Pacific scooped seven Tony Awards, including musical revival, at Sunday's ceremony.
The show also picked up best director, four design awards including set, costumes, lighting and sound and Paulo Szot took best musical leading actor.
In the Heights was named best musical while Pulitzer Prize-winning August: Osage County won best play.
The 62nd annual ceremony, hosted by Whoopi Goldberg, was held at Radio City Music Hall in New York.
In the Heights was awarded three more prizes including best original score for the theatre, best choreography and best orchestrations.

The original production of South Pacific - composed by Richard Rodgers and Oscar Hammerstein II - won nine Tonys in 1950.
Bartlett Sher, who oversaw the show, thanked Rodgers, and Hammerstein, along with original director Joshua Logan and James Michener, who wrote the Pulitzer Prize-winning Tales of the South Pacific, the collection of short stories which inspired the production.
"They were incredible men, because they seemed to teach me that in a way I wasn't only an artist, but I was also a citizen," Sher said.
Gypsy, which was South Pacific's main competition, took three of the four musical performance awards.
Patti LuPone received a rousing ovation as she won the actress-musical prize for her performance as Rose, an indomitable stage mother.
"It's such a wonderful gift to be an actor who makes her living on the Broadway stage and then every 30 years or so picks up one of these," said LuPone.
It was her second Tony after winning her first award in 1980 for playing Eva Peron in Evita.
LuPone's co-star, Boyd Gaines, collected his fourth Tony, winning for his portrayal of Rose's gentlemanly suitor, Herbie.
Laura Benanti, who plays the ugly-duckling daughter who blossoms into Gypsy Rose Lee in the show, received the featured actress award.
