Heard this morning at the start of a feature on the 'Today' programme
"The singing is to soothe the yak."
Only the BBC could produce a line like that. In fact it was a feature about a British doctor working in a peaceful area of Afghanistan.
See if you can catch it at http://www.bbc.co.uk/today It should be available online for 7 days in the archive section (Look up 8-40am on Tuesday Sep 11)
