Theodore recorded TWO albums, both very rare and expensive. They are
"Entertainment of Sinister and Disconcerting Humor" (released
in both ten inch and twelve inch formats) and "Theodore (in Stereo)." A 45 rpm single was released by PIP (PIP 8918) featuring a beatnik-drum version of Lisolotta Binde (which is loosely based on Poe's "Berenice") backed with I'm Just Plain Folks, which is basically a mini-monologue featuring some of his more infamous lines. It was played at his funeral.
On CD, Theodore's re-telling of "Berenice" (originally on the Coral album) is available on a Rhino compilation called "Scary Stories," a peculiar compilation of mostly straight (and mostly Poe) tales. If you are feeling peevish, contact Rhino, Varese Sarabande and Razor & Tie and demand that they re-issue Theodore's work, and send Royalty Checks.
