Watch out for a family affair on Sunday night at the Garrick Theatre for the one-night-only, post-Edinburgh engagement of Frances Ruffelle’s new concert show Beneath the Dress. Ruffelle’s daughter by director John Caird, chart-topping pop star Eliza Doolittle (no guesses where the parents got their naming inspiration), has tweeted that she’ll be joining mum onstage for a duet. It’ll be the first time that mother and daughter have performed together on a West End stage since Les Miserables when Frances played Eponine and an eight-year-old Doolittle played Cosette.

Doolittle won’t be the only special guest. After her drop-in at the show during its Edinburgh Fringe season last month, Sadie Frost will again be on hand for another duet with Ruffelle. They plan to sing “Best Friend” from Michael John LaChiusa’s 2000 Broadway musical The Wild Party.
