Producers are billing an Ulster-Scots epic “On Eagle’s Wing,” being staged in Belfast, as the biggest theatrical production in the world. The show “has a distinctly international flavour with a 100-strong cast and crew, as well as a choir of 300 and an orchestra. Featuring West End star Peter Corry and Scotland’s Alyth McCormack, the musical traces the journey of the Scots-Irish to the US 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 sq ft stage, using one of the largest light sets ever constructed.”
