A long time ago, we reviewed Rick Springfield's 1973 series for Filmation & ABC, Mission: Magic. Now, you know that Rick also recorded the show's theme song. Not just the usual minute-or-less ditty you usually get on a Saturday morning show. In this case, that was an edited version of the actual song, which I think Rick also wrote and released on an album coinciding with the series' debut.
Until today, I'd never run across the complete version of that song, but here it is. Unfortunately, there's only a photo of the album cover. No series footage.
