"Father and Son" is a popular song written and performed by English singer-songwriter Cat Stevens (now known as Yusuf Islam) on his 1970 album Tea for the Tillerman. The song frames an exchange between a father not understanding a son's desire to break away and shape a new life, and the son who cannot really explain himself but knows that it is time for him to seek his own destiny. Stevens sings in a deeper register for the father's lines, while using a higher one for those of the son. Additionally, there are backing vocals provided by Stevens' guitarist and friend Alun Davies beginning mid-song, singing an unusual chorus of simple words and sentences such as "No" and "Why must you go and make this decision alone?"
