Once the Tony Award -winning stage musical is to transfer from Broadway to London's West End next January.
Based on the 2006 Irish film about a struggling busker who falls for a Czech immigrant in Dublin, it won eight Tony Awards including best musical this past June.
The story of the musicians' love affair is told through the songs they write.
Once will replace Blood Brothers at the Phoenix Theatre where it has run for more than two decades. It will follow a brief run of Goodnight Mr. Tom.
