Broadway and Glee star Jonathan Groff will lead the cast of the How To Succeed In Business Without Really Trying concert at the Royal Festival Hall on 19 May 2015.
The WhatsOnStage Award winner – for his role in Deathtrap in 2010 – will play J. Pierrepont Finch in the concert, which is directed by Jonathan Butterell with musical direction by Mike Dixon. Groff is currently starring in Hamilton at the Public Theater in New York.
Musical theatre regulars Hannah Waddingham (Kiss Me, Kate, A Little Night Music) and Clive Rowe (The Light Princess, Kiss Me, Kate) will play Hedy La Rue and Twimble in Frank Loesser's musical.
The show will feature the Royal Philharmonic Orchestra, and is produced by Senbla in association with Elliot Davis.
Tickets for the concert are on sale now.
