Oh my god!! - go and watch it immediately!
Back in 1990 Sky TV showed all the original series - including an episode or two that were never shown originally in the UK - it was on at 21:00, and repeated the following afternoon.
Anyway, on 4th September 1990 they were showing one of the 'never seen in the UK' episodes, then at about 6:00 in the morning my wife went in to labour, we spent all day in the hospital, and our daughter was born about 22:00 (so I missed the episode). No problem I thought, when I got home I set it to record the next afternoon
What did I get - cricket - it was the
ONLY episode not shown again the next day, because there was a stupid cricket match on!
I've since downloaded the missing episodes, and indeed all the original series
