Country Meets Folk was mentioned in another thread the other day (b*gg*red if I can remember which thread though).

Yes, I have many happy memories of attending the recordings as an audience member (in the Playhouse Theatre, near what is now Embankment tube station). I saw many top artists there, even if they only sang a few songs each (of course I saw many of them elsewhere too, but CMF was a free concert each time!)
