The mop-topped fab four from Liverpool conquered the world with catchy, feel-good hits like this song “I Feel Fine” from 1964. In the video, you can catch the Beatles' sense of humor, with George pretending to sing the wrong words and Ringo riding a bicycle instead of playing the drums.

The production of the song "Now and Then" took place over five decades and is the product of conversations and collaborations between the four Beatles that go on to this day. The long mythologized John Lennon demo was first worked on in February 1995 by Paul, George and Ringo as part of The Beatles Anthology project but it remained unfinished, partly because of the impossible technological challenges involved in working with the vocals John had recorded on tape in the 1970s.
