I checked the Journal Graphics database, which indexes transcripts
of news programs on ABC, CBS, CNN, NPR and others; neither gregorian
chants nor scottish dancing showed up for a recent transcript. I don't
know how far behind the index is. It's free: telnet to database.carl.org,
and wiggle through the menus. This is the same company that is shown
at the end of shows like Nova and Nature, "For a transcript of this
program, send $4 to..." etc. You can order transcripts over the Internet
connection by giving them a credit card, I think. Either that or it will
show an 800- number to dial free in the US.
If I have occasion to be in a full-text transcript database, I'll look
again; the Journal Graphics index is only an index.
You can get video copies from the news programs, but it's very much like
pulling teeth and considerably more expensive.
I think that the story we are trying to track down was played on Friday
night last week, not Saturday, which would explain why the weekend news
staff could not find any references to it. See if the Friday report does
not have the references.
