The Ulster-Scots epic has an international flavor with a 100-strong cast and crew, and a choir of 300 and an orchestra, the BBC reported.
The musical, featuring West End star Peter Corry and Scotland's Alyth McCormack, traces the journey of the Scots-Irish to the United States and examines their influence on American music and culture.
More than 400 costumes will be worn during the show which is set on a three-storey, 4,800 square-foot stage, using one of the largest light sets ever constructed, the BBC said.
The musical was to premiere in Atlanta in the United States this month but could not due to financial problems.
Ian Kennedy, the musical's chief executive,said he is confident the show will return to the United States next year.
"This is the biggest theatrical show in the world - at this moment - and is a truly amazing show set in historical Scotland, Ulster and America and finishing with a spectacular celebration of all three in the present day," he said.
