guarantee I’ve never programmed a White Album without “I’m So Tired,” with John’s whisper-to-a-scream vocals, so funny yet so harrowing. Paul joins in for the last line, doing the John imitation he also does so well in “Come Together.” The song is over in less than two minutes, both men wildly amused by one another, even as John screams “I’m going insane!” What an intense moment it must have been to share a laugh like “I’m So Tired.” To get blazed up by that comic presence. And to lose this presence, and know you’re losing it, to see it slipping away right in front of you.
