Maybe it's a truism that most instrumental music, at least before World War One, aspires to the condition of song. Few have gone farther in that respect than the composers of the three purely orchestral works in last night's Prom. Add to the mix a conductor of impeccable operatic credentials who knows how to draw intimate vocalising from his players, a promising lyric-dramatic pianist and one of the most unusual great soprano voices of our time, and an evening of singing heartbreak was the result.

It’s not often you find yourself in an art gallery with the business end of a bullwhip whizzing inches from your nose. Wielded by a disconcertingly slight, black-haired woman who can barely be half its length, the terrifying instrument defines the dimly lit space with its whirling undulations and earsplitting crack, sending the gaggle of spectators cowering into adjacent rooms. Why there is also a grand piano present is probably only entirely known to the unnamed artist who brought this trickily titled exhibition into being.

“It’ll be tricky to write about,” said the man next to me last night, a Cubaphile. “It's the good, the bad and the awful.” The Cubans’ second programme, The Magic of Dance, is an old-fashioned warhorse of showstoppers from the classics, a tapas bar of Giselle, Sleeping Beauty, Nutcracker, Coppelia, Don Quixote, Swan Lake and Gottschalk Symphony. Come again, the last one? It’s a company conga by Alicia Alonso. Enough said.

Dave Gorman, it could be said, invented a genre of comedy. His reality-based documentary tales - about hunting down people with the same name or finding unique Google searches - were meticulously researched and generously illustrated; he was the king of PowerPoint. But here he has returned to his stand-up roots and while the show has a title - Sit Down, Pedal, Pedal, Stop and Stand Up- it has no central theme and is not, like those before, delivered almost as a lecture.

Lesley Sharp could be thought of as an actor's actor: a talent equally at home in theatre, cinema and TV who has been impressing audiences and critics regularly for a quarter-century without quite becoming a star name.
