Awesome Music: Not just the tune itself, but the fact that, in the many decades that he's performed this song, Arlo consistently manages to recite 18+ minutes of dialogue and play an intricate guitar melody without missing a single note!
At one performance, he actually forgot the words and managed to get by ad-libing random thoughts for several minutes while still playing the guitar flawlessly.
Can you imagine, three people walking in, singin a bar of "Alice's Restaurant" and walking out. They may think it's an organization. And can you, can you imagine fifty people a day, I said fifty people a day walking in singin a bar of "Alice's Restaurant" and walking out. Then, friends, they may think it's a movement.
Values Dissonance: Arlo says that if two people sing the song as protest, "they'll think you're a couple of faggots." That kind of language wouldn't fly in today's polite society.
Amended on the 30th anniversary performance of the song.
"I don't care what the president says, unfortunately to a lot of people, that's still a problem!"
Wild Mass Guessing: The main proponent of "Nixon's mising 18 minutes contains 'Alice's Restaurant'" is Arlo Guthrie himself.
