As before, the soundtracks have been assembled from the best possible sources - thanks in particular to a8detective, Trkizbrki and BlackwatchPlaid here at LMT, jakej at the Internet Archive, and the Audio Only YouTube channel for sharing the missing episode soundtracks.
Hope you enjoy them - Usher in particular is a spectacular body of work!
