Yoko Ono – musician, artist, activist and the 92-year-old widow of the late John Lennon – took the brunt of the vitriol when The Beatles broke up in 1970, and details revealed in a new documentary film “One to One: John & Yoko” highlight her personal struggle.

The relationship between The Beatles star John Lennon and his wife Yoko Ono forms the main focus of a new documentary highlighting the couple's charity work, their love, and their family in the run-up to Lennon's death.

In an interview with Q's Tom Power, author David Sheff explains why he thinks we should be thanking the Japanese artist for keeping the Beatles together longer.
