There are some archived programmes but not as far as I know any of the Folky ones. I think the extra cost for permission to do iplayer type things on commercial recordings is beyond the stations immediate finances.

Will check again when in there this week.

There is also a show on Tuesdays between 1 and 2 pm presented by Sam Lee based around his Magpies Nest collective musical activities.

Shows are often randomly repeated during mornings including weekend times but not to a schedule.
