O’Byrne rose to fame in chart-topper Will.i.am’s team after becoming the first classical singer to reach BBC One’s The Voice final.
She will star in the Bill Kenwright-produced revival of The Sound of Music which opens on 2 December 2015 at the Broadway Theatre, Peterborough before embarking on a major UK tour.
The memorable score features songs including, “My Favourite Things”, “Do-Re-Mi”, “Climb Ev’ry Mountain”, “So Long, Farewell” and the title song, “The Sound of Music”.
Directed by Martin Connor with choreography by Bill Deamer and musical direction by David Steadman, the production coincides with the 50th anniversary of the iconic film version starring Julie Andrews.
