How? is a song from the album that was released after which first solo Lennon release?
How? (song) "How?" is a song from John Lennon's second solo album "Imagine", released in 1971. It is a contemplative song inspired by the Primal Therapy he was undergoing with his wife Yoko Ono, during which he faced many personal questions such as "How can I go forward when I don't know which way I'm facing?" This song also shows his thoughts about the world in general (such as "And the World is so tough; Sometimes I feel I've had enough").
She's Leaving Home "She's Leaving Home" is a Lennon–McCartney song, released in 1967 on the Beatles album "Sgt. Pepper's Lonely Hearts Club Band". Paul McCartney wrote and sang the verse and John Lennon wrote the chorus, which they sang together. Neither George Harrison nor Ringo Starr was involved in the recording. The song's instrumental background was performed entirely by a small string orchestra arranged by Mike Leander, and was one of only a handful of Beatles songs in which the members did not play any instruments on the recording.
