I Want To Hold Your Hand

"I Want To Hold Your Hand" was the first to sell one million copies on British advance orders alone ! It is best-selling Beatles single worldwide and the first Beatles song to top the USA charts

Epstein was worried about The Beatles' lack of commercial success in America—their earlier singles had flopped there—and so he encouraged Lennon and McCartney to write a song that would appeal to American listeners  McCartney had recently moved into 57 Wimpole Street, where he was living as a guest of Dr. Richard and Margaret Asher. Their daughter, Jane, had become McCartney’s steady girlfriend since first meeting earlier in the year. This location briefly became Lennon and McCartney’s new writing base, taking over from McCartney’s Forthlin Road home in Liverpool.^[4] Margaret Asher taught music in a “small, rather stuffy music room” in the basement and it was here that Lennon and McCartney sat at the piano and composed 'I Want to Hold Your Hand'. In September 1980, Lennon told Playboy magazine: 'We wrote a lot of stuff together, one on one, eyeball to eyeball. Like in 'I Want to Hold Your Hand,' I remember when we got the chord that made the song. We were in Jane Asher's house, downstairs in the cellar playing on the piano at the same time. And we had, 'Oh you-u-u/ got that something...' And Paul hits this chord, and I turn to him and say, 'That's it!' I said, 'Do that again!' In those days, we really used to absolutely write like that—both playing into each other's noses'
