Like many of the White Album’s tracks, “Sexy Sadie” dates from the Beatles time in India studying under the Maharishi Mahesh Yogi. During this period, rumors began circulating that the Maharishi had been seducing female devotees (according to Paul McCartney, Alex Mardas — better known as “Magic Alex” — informed the group of the gossip). Disenchanted, the Beatles decided to leave, with John Lennon feeling the most betrayed.
As he told Rolling Stone in 1971, “So, we went to see Maharishi, the whole gang of us, the next day, charged down to his hut, his bungalow – his very rich-looking bungalow in the mountains – and as usual, when the dirty work came, I was the spokesman – whenever the dirty work came, I actually had to be leader … and I said ‘We’re leaving.’ ‘Why?’ he asked, and all that shit and I said, ‘Well, if you’re so cosmic, you’ll know why.’”
