If you want to recreate the OBV of those two episodes, use the Kaleidoscope 1985 VHS versions, or if you want to have a nameboard sequence, use the 1988/1992 versions.
I definitely want a nameboard sequence in between “Percy Runs Away” and “Coal”, just like every other pair of episodes from Series 1 and 2, so where can I find the 1988 or 1992 re-releases of the Kaleidoscope VHS tapes? Thank you.
