Almost all is familiar with the song "Imagine", the best-selling single of the former member of the Beatles, the late famous singer John Lennon. The US National Music Publishers Association announced in an industry event in New York on June 14 that the widow of John Lennon, Yoko Ono, co-owned the copyright for this song. Since the first release of the song in 1971, it has been late for 46 years.

According to reports of BBC, extracts of an interview with Lennon was broadcast in the event ceremony. In the interview Lennon said that "a lot of it ['Imagine'], the lyrics and the concept, came from Yoko... Those days, I was a bit more selfish, a bit more macho, and I sort of omitted to mention her contribution."
