Haven't heard it myself, but that would be "Songs Of Robert Burns" Sung by Ewan MacColl" : Folkways Records FW 8758, if that helps.
I would have preferred hearing MacColl sing Burns to anyone I heard on that programme on Saturday night. Katie the piper was the star for me - a true inspiration to anyone. And I liked the police inspector's contribution too.
Alistair Heather may mean well, but as far as I'm concerned, what he is required to do on these programmes is a national embarrassment. Most likely the programme's producers to blame rather than him. I have no animosity towards him personally.
