On the day they returned from the Toronto Rock and Roll Revival festival, John Lennon and Yoko Ono gave an interview to a camera crew from ITV News. The interview took place at Apple Corps, 3 Savile Row, London, and was broadcast the following evening in the UK. It focused on the debut performance by the Plastic Ono Band in Toronto.Lennon spoke about assembling the band quickly, and how rock musicians were eager to jam with one another whenever possible rather than being confined within bands. Asked whether it marked the beginning of a solo career, he said he would play it by ear.The reporter asked the couple to define their “howling” sound. Ono described it as “an expression that’s not so intellectualised as words”, while Lennon said it was simply “pure sound”. They then gave a vocal demonstration.
