"Yes I Will", also known as "I'll Be True to You", is a song written by Gerry Goffin and Russ Titelman.

The song was first recorded in 1964 by British Beat group the Hollies who released it as a single in January 1965 where it peaked at number 9 in the United Kingdom that April.

An alternate take with prominent acoustic guitars and a different intro was included on the band's 1968 greatest hits album in the UK.

While a top 10 hit in the UK, it failed to chart entirely in the US and Canada where it was released two months later on the Imperial and Capitol labels, respectively.
