John (Winston) Lennon (1940 - 1980)
In 1970 the album John Lennon & The Plastic Ono Band came out. This first serious song album after the Beatles's break up meant a shock for lots of Beatles fans, it included not only personal confessions but also confessions about Lennon's struggle with Beatles.
Imagine, the titlesong of his second album has become the most covered solo Lennon song.
