It's playing on Radio Margarittaville tonight, and the Vault has this going:

The Vault continues the tradition of bringing you Arlo Guthrie’s Turkey Day ritual Alice’s Restaurant Massacree on Thanksgiving – but this time Arlo has "updated" this classic, and you’ll get it NON-STOP all Thanksgiving Day – that way no matter what time zone you’re in or what time you’re feasting you’ll get a bountiful supply of this Turkey Day classic!
God I love Sirius. Too bad I got the Grateful Dead marathon going all day.

I might check out the Vault's thing later on.
