Audio of Casey at the Bat and two unauthorized sequels

Telltale Weekly, which sells DRM-free audiobooks of public domain works, has just posted a $0.50 version of "Casey at the Bat" and two "sequels" written by a different writer, hearkening to an era when copyright didn't mean that others couldn't fool around with your work.

Ernest L Thayer (writing under the pen name "Phinn") wrote the baseball classic Casey at the Bat: "A Ballad of the Republic, Sung in the Year 1888" for the San Fransisco Examiner. In the century since, the poem has spawned hundreds of sequels, including a handful of updates by sports columnist Grantland Rice.
