By the summer of 1974, John had been living apart from Yoko for nearly a year. Quartered in Los Angeles he entered a boisterous spell tagged Lennon's Lost Weekend. Like its predecessor 'Mind Games', the new album would be self-produced. As to the musicians, among familiar names like Jim Keltner, Klaus Voormann and Nicky Hopkins and a couple of luminary guests that included Nilsson and the hottest rock star of the moment, Elton John. It was Elton who spotted the chart-topping potential of 'Whatever Gets You Thru The Night', a storming track to which he contributes. Indeed he won his friendly bet that this song would be Lennon's first solo Number 1 - for which his 'price' would be a guest appearance by John at Elton's Madison Square Garden show.
