I saw Arlo and Abe almost two years ago in Socorro, NM, and Arlo explained in reasonable tones why he would NOT sing "Alice's Restaurant". And he didn't. Fine with me (because he did sing "Good Morning, America"). Also, he abbreviated "Whoopee-ti-yi-yo" and "This Land is Your Land". I suspect he may be getting tired of them, too.

They were non-folk musicians. I have a feeling someone's going to come up with two completely different people from the ones I've heard this attributed to, and we'll have to figure out which one is an urban legend.
