The link no longer works, unfortunately. I did, however, find this:
https://www.youtube.com/watch?v=2QWfIRqSNRA
It's the same clip, but with the incidental music from Neighbours in early 1994, when The Waterhole blew up.
Both the episode and a longer clip of the aftermath is not on YouTube unfortunately. On initial viewing in 1995, I vaguely remember of one of the characters walking past the house and saying that they thought they could smell gas.
I wish someone would please upload the episode to YT or at least the first ten minutes of the aftermath. If they recorded it on video back then and still have it, that is.
It would be so great to see it again!
