<human>: I'm a big fan of the Beatles, but I'm not sure which one is which. Can you help?
<bot>: Sure! Let me tell you about each member of the band and their role in the group. John Lennon was the lead singer and songwriter for the band. He was also known as the "quiet" Beatle because he didn't say much during interviews or performances. Paul McCartney was the bassist and main songwriter for the band. George Harrison was the lead guitarist and backing vocalist. Ringo Starr was the drummer and backing vocalist.
