Jude,

I'm not sure if BBC4 have any programing available on the web.

If you have access to digital TV then keep an eye on the listings for BBC4 in the next week or so, as they tend to repeat stuff late at night for a while after it is originally shown.

Some of their programs also turn up later on the terrestrial channels, maybe late night on BBC2. I'm not sure if they've reshown Folk Britannia on BBC 2 yet, but it often happens.

If, as I suspect, you've been a follower of Irish Music down through the years, you probably won't find too many surprises in there, but it is a good program none the less.
