"With All My Heart" is a popular song, based on an originally French and Italian language song called "Gondolier." It was written by Peter De Angelis and Bob Marcucci.
While it was the only major hit for Jodie Sands in the United States (reaching #15 on the Billboard magazine Pop Singles chart in 1957), in the United Kingdom it was one of a number of hits for Petula Clark (#1 in the Belgian chart, #4 on the UK chart[1]) before she became known in the USA.
