London Town (also known as My Heart Goes Crazy [3]) is a 1946 Technicolor musical film directed by Wesley Ruggles and starring Sid Field and Petula Clark.

As he was of the opinion that no British director was capable of making a good musical, he insisted on having an American at the helm, and the task fell to Wesley Ruggles, who produced as well.

[6] Given that Ruggles had no experience with the genre – his best-known films at that point were the Academy Award-winning Western epic Cimarron (1931) and the Mae West comedy I'm No Angel (1933), both more than a decade old – and his Hollywood career was on a downslide, he was an odd choice indeed.

[8] J. Arthur Rank spent large sums of money for American songwriters (Jimmy Van Heusen and Johnny Burke), musicians (Ted Heath and his orchestra), and costumes by the legendary designer Orry-Kelly, while at the same time re-equipping the studio from the ground up.

He was confident that box-office business was booming at the time and that demand for a flashy musical entertainment would be such that he would make a healthy profit, so his financial controls were slack.

In hindsight, however, especially for nostalgia fans, many of its kitschy aspects make it fascinating, and film historians consider it an interesting record of the times in which it takes place.

Following Britain's victory in the war, it can be seen as a tribute to London and its residents, and as a celebration of popular Cockney culture, especially its music hall traditions.

"[8] Ruggles and Guest were going to make a film together about the Rolls Royce family but those plans ended after the financial failure of London Town.

Songs in London Town include "You Can't Keep a Good Dreamer Down", "The 'Ampstead Way" (most definitely inspired by "The Lambeth Walk" from the earlier stage production Me and My Girl), "Any Way the Wind Blows", a medley of Cockney songs ("Knock 'em in the Old Kent Road"/"Any Old Iron"/"Follow the Van"), "Don't Dilly Dally on the Way" (sung by Charles Collins), and "My Heart Goes Crazy", which was the title under which an abridged U.S. version of the film was released by United Artists in 1953.
