Title: Theme to St. Trinian's

"Theme to St Trinian's" was later re-recorded by the Banned of St Trinian's; this appeared on the soundtrack to St Trinian's 2: The Legend of Fritton's Gold and was also produced by Xenomania. Coincidentally, Girls Aloud member Sarah Harding had a starring role in the film. A music video for the song was released to music video stations to promote the film and the soundtrack. The video consists of Girls Aloud performing the song at the end of the movie, as well as various clips of other scenes from throughout the film.

Title: The Belles of St. Trinian's
Content:  The New York Times wrote, "Credit Alastair Sim with doing excellently by the dual roles he essays...Joyce Grenfell makes a properly gangling, awkward and gullible lady sleuth; George Cole does a few delightful turns as the conniving Cockney go-between and last, but not least, the 'Belles of St. Trinian's' rate a vote of confidence for the whacky freedom of expression they exhibit. They all help make St. Trinian's a wonderfully improbable and often funny place to visit."
Title: St Trinian's (film)
Content:  St Trinian's received mixed reviews. Empire wrote that the film "fuse[s] an understanding of what made the originals great with a modern feel – the writers have fulfilled their end of the bargain, even tweaking some of the weaker points of the original story." The Observer wrote that it "is raucous, leering, crude and, to my mind, largely misjudged, with Rupert Everett playing Miss Fritton as a coquettish transvestite with the manners of a Mayfair madam.
