THREE months after the series has ended it seems certain that STV's A Song for Scotland competition has been a success. When he launched the contest STV's Programme Controller Francis Essex said he hoped it might "discover a song that will... truly reflect Scotland one that will be whistled and sung all over the country. "Not only did we get that song Roy Ford's beautiful "Loch Maree" we got another in "These Are My Mountains'*, the runner-up, and we're delighted with the success they've brought the artists who recorded them," says Francis. Moira Anderson, whose rendering of "Loch Maree" won the contest, has had considerable success with her recorded version, backed by "These Are My Mountains", which was written by Jimmy Copeland. Four different recordings have been made of "These Are My Mountains". For apart from Moira's there are versions by the Alexander Brothers. Peter Mallan and the Jim McLeod Band. In seven weeks the Alexander Brothers' record has sold over 20.000 copies, and the song is also featured on and supplies the title for their new L.P. Peter Mallan, who sang it on the pro gramme, has sold over 10,000 copies of his version.   The Stage, June 1966.
