What was john Lennon position in the group?

Lennon was the rhythm guitarist, although he occasionally played keyboards, bass and lead guitar on some tracks.

In the early days of the band, he was seen as the leader; Paul McCartney has acknowledged Lennon as "the guy you wanted to sit next to on the bus". Lennon was also the main songwriter in the band until around 1965; he wrote 11 out of the 14 songs on A Hard Day's Night.

Later his role diminished a little; during the studio years, McCartney's musical skill brought him more to the fore in the band.

Brian Epstein described Lennon as "the mind of The Beatles".
