The Scarecrow's Mirage
The Scarecrow has always been one of my favorite Batman villains. Partly because of the character itself--he's got a great hook and a great look, but also because (IMO) he was so generally ignored, at least compared to The Joker, Catwoman, etc.--he never appeared in the 1960s TV show, and nor did he in the first set of Batman films.
But Power Records clearly liked him, picking him above bad guys like Two-Face and The Penguin for a shot at audio glory. And they did a really good job on the characterization--whoever plays the Scarecrow sounds like his voice is coming through a burlap sack, a great, creepy touch. The story itself isn't all that scary, but that didn't bother me as a kid, as I played the Batman LP it appeared on over and over.
I never had this single 45" release of it--and that's too bad, because the Neal Adams sleeve is, of course, a killer (no pun intended)!
