Dan sez, "The swell blog 'Isn't Life Terrible' has a small yet perfectly formed collection of non-Disney Disney songs available for download, including an apparently non-ironic ditty about how nifty it is to be a Walt Disney World annual passholder (or, as the Disney cast members will call you, 'passhole'). There are also couple of choir numbers from Rev. Billy's Church of Stop Shopping, spoken bits, and a nice parody of Randy Newman's transformation from a snarky satirist into the sappiest Disney songwriter since Mousketeer Jimmy Dodd."
(Thanks, Dan!)
