"(I'm Watching) Every Little Move You Make" is a song, written by Paul Anka and originally recorded by British singer Jimmy Cassidy in May 1963 as the B-side to his cover of the Nacio Herb Brown standard Paradise, followed by a cover in late 1963 by Little Peggy March for her debut album, I Will Follow Him, that was a minor hit on the charts in 1964. Anka himself also released his own version in October 1963 as a single in France.
In the same year, it became (under the title I'm watching) a hit for French singer Sylvie Vartan, who released it both in English and in French (under the title "Je ne vois que toi" on her 1963 album Twiste et chante) in August 1963.
