This song is often interpreted as a tribute to Syd Barrett, though the original concept behind its lyrics was different. The music itself flows as if tuning a radio through various stations, eventually landing on the song, with a twelve-string guitar intro processed to sound like it's coming from an AM radio. This creates the impression of a guitarist listening along and joining in as the broadcast fades. Ultimately, the song transitions into light, high scat singing and wind sounds before segueing into "Shine On You Crazy Diamond." It plays like a heartfelt reflection, full of a longing presence.
