I'm So Tired by The Beatles

"LENNON: [...] That was the competition in Maharishi’s camp: who was going to get cosmic first. What I didn’t know was I was *already* cosmic. [Laughs.] ... PLAYBOY: “I’m So Tired”? LENNON: “I’m So Tired” was me, in India again. I couldn’t sleep, I’m meditating all day and couldn’t sleep at night. The story is that. One of my favorite tracks. I just like the sound of it, and I sing it well." (All we are saying, p. 199)
