The production celebrates its second birthday at London's County Hall.
Having already confirmed West End’s Ria Jones (Cats, 42nd Street, Les Miserables), and Strictly Come Dancing finalist Danny Mac, further cast members have now been announced for the Sunset Boulevard UK tour.
Adam Pearce (Les Miserables), Molly Lynch (Sweeney Todd), Dougie Carter (La Cage Aux Folles) and Carl Sanderson (Cats) will join the cast.
Jones first took on the role of Norma in the West End as understudy to an unwell Glenn Close. Her involvement in the production goes back to 1991 when she supported Andrew Lloyd Webber at a developmental workshop.
The show tours the UK, arriving at the Birmingham Hippodrome Theatre on the 13 November 2017.
