What was the name of John Lennon's first solo single?

“What was the name of John Lennon’s first solo single?” — “Give Peace a Chance.” Lennon released the song in July 1969, while the Beatles were still officially active. The single was credited to the Plastic Ono Band and appeared on Apple Records, but it is widely recognized as Lennon’s first solo single.

Lennon wrote “Give Peace a Chance” with Yoko Ono during their Montreal Bed-In for peace. The phrase came from Lennon’s spontaneous response when a reporter asked what he was trying to achieve by staying in bed. On 1 June 1969, Lennon, Ono, and a group of visitors and journalists recorded the song in Room 1742 of Montreal’s Queen Elizabeth Hotel.

The recording became an anthem of the anti-war movement, particularly protests against the Vietnam War. Its simple chorus made it easy for large crowds to sing, and hundreds of thousands of demonstrators used it at public rallies. A technical detail sometimes causes confusion: the original record credited the song to Lennon–McCartney, although Lennon later regretted not crediting Ono more directly. “Instant Karma!” was another early Lennon solo hit, but it came later, in 1970.
