Orchestral Manoeuvres [Orchestral Manoeuvres in the Dark] [OMD]: Joan or Arc (1981)

Oddly, this Canadian 12" single is credited to Orchestral Manoeuvres, rather than Orchestral Manoeuvres in the Dark. I wonder why. It contains Joan or Arc, from Architecture and Morality as well as The Romance of the Telescope (Unfinished), a track that later appeared in finished form on Dazzle Ships.
