"You talk like Marlene Dietrich, you dance like Zizi Jeanmaire, your clothes are all made by Balmain, and there’s diamonds and pearls in your hair…" . Peter Sarstedt may have been a one-hit wonder, but his 1969 pop song, "Where do you go to (my lovely)?" passed into British popular culture in a flash, even if many of its chic references were lost on future generations. Zizi Jeanmaire, who died last Friday aged 96, personified the Paris of the 1940s, 1950s, 1960s, and beyond.

Loosely inspired by Joan Crawford, it’s the ultimate anthem of showbiz survival.

Some wondrous acting is sacrificed on the altar of an increasingly wonky plot in On Blueberry Hill, the first play in 10 years from Sebastian Barry, the Irish playwright and novelist whose onetime Royal Court entry The Steward of Christendom showcased a treasured theatrical memory in the leading performance of the late and truly great Donal McCann.

It’s not so much that Pretty Woman: The Musical isn’t much good, which it isn’t.

The theatre gods rained down not fire and pestilence, but a 45-minute technical delay on opening night of this substantially revised musical – a stage adaptation of the 1998 DreamWorks animated movie.
