The Edinburgh Festival provides a colorful background for this lively musical comedy. When penniless dancer Janet Jones (Vera-Ellen) emerges from a limousine at the festival, she's mistaken for the girlfriend of the car's millionaire owner - when in fact, she'd only hitched a ride with the driver. Suddenly Broadway director John Frost (Cesar Romero) wants her in his next musical in order to get financing from this "millionaire boyfriend." Soon Janet is romanced by B.G. Bruno (David Niven), the limo's real millionaire owner. The musical numbers include "One-Two-Three," "Would You, Could You," and "London Town." Filmed in England, the Happy Go Lovely cast is filled with popular British stars such as Bobby Howes, Joyce Carey and Kay Kendall.

In this fine musical comedy, the producer of a big Broadway show hires a chorus girl for the dubious reason that her boyfriend is a millionaire. His financial support would be of invaluable assistance to the floundering production.
