When Lennon/McCartney wrote "World Without Love" they decided to give it away immediately, they thought it was too corny!
Who better to get it than Peter and Gordon, especially when Peter Asher was the brother of Jane Asher, Paul's steady girlfriend at the time.
McCartney also wrote "Woman", "Nobody I Know" and "I Don't Want To See You Again" for Peter and Gordon. For "Woman" he used the name "Bernard Webb" to see if he could have a hit without anyone knowing it was him, but everyone figured it out anyway.
BTW, Asher later became a very successful manager of artists such as James Taylor, Linda Ronstadt, JD Souther, and Bonnie Raitt.
