"Jesamine" is a song written by Marty Wilde and Ronnie Scott, published under the pseudonyms Frere Manston and Jack Gellar.

[3] Scott initially conceived "when Rosemary goes" as the first line of the chorus; Wilde suggested the name be changed to Jesamine, the name of a cafe in Huyton, Merseyside, where his mother-in-law lived.

[4] Wilde, who had been a teen idol, was keen to "know what reaction there was to the song" before disclosing his identity.

The song was then recorded by the Casuals based largely on the Bystanders' arrangement, and released as "Jesamine".

"[1] In 1969, "Jesamine" received the Ivor Novello Award for Most Romantic Song of the Year.
