"I'm So Tired" is a song by the English rock band the Beatles from their 1968 double album The Beatles (also known as "the White Album"). It was written and sung by John Lennon, though credited to Lennon–McCartney. Lennon wrote the song during the Beatles' stay in India about insomnia he was having due to constant meditation and because he missed Yoko Ono. The song was recorded in the same session as another White Album song, "The Continuing Story of Bungalow Bill". Composition Lennon wrote the song at a Transcendental Meditation camp when he could not sleep; the Beatles had gone on a retreat to study with the Maharishi Mahesh Yogi in Rishikesh, India. After three weeks of constant meditation and lectures, Lennon missed Yoko Ono, with whom he had yet to start a relationship, and was plagued by insomnia, which inspired the song. One of dozens of songs the Beatles wrote in India, "I'm So Tired" detailed Lennon's fragile state of mind. It was also an open letter to Yoko Ono, whose postcards to Lennon in India were a lifeline. "I got so excited about her letters," he said. "I started thinking of her as a woman, and not just an intellectual woman." Lennon later said of it: "One of my favourite tracks. I just like the sound of it, and I sing it well". During the second verse, Lennon calls Sir Walter Raleigh "a stupid git" for introducing tobacco to England. The theme of insomnia complements Lennon's earlier song "I'm Only Sleeping" on the Revolver album. The song is in the key of A major. Recording An early demo of the song was recorded at George Harrison's Esher home, in May 1968. It was basically identical to the released version, in terms of verse, but it does include a spoken section reminiscent of a similar section in "Happiness Is a Warm Gun". It goes: This section was probably improvised at the time, as it was never used again. The song was recorded on 8 October 1968 and was completed including all overdubs in this one session. The Beatles also started and completed "The Continuing Story of Bungalow Bill" during the same recording session. The chorus of the monaural mix of the song features louder backing vocals from Paul McCartney than the stereo mix. The Beatles later performed the song, with Paul McCartney singing lead vocal, in a jam
