From memory Ten had normal programming at 7.30pm with The Simpsons. Neighbours didn’t air on September 12 so I presume there was news coverage at that time. I do remember they made up for the missed episode that night with a special hour episode of Neighbours on September 14.

And from this YouTube video channel surfing on September 12 it looks like Ten played Ed at 8.30 that night but then at 9.30 they went back to news coverage. The Panel didn’t air that night either.
