Regarding Fiondel's third item, I must point out that songs shared on the physical medium of the CDs are SLIGHTLY more under the control of the authors of the songs. When we put out the second CD, we promised the authors that we wouldn't put their songs on the internet, where anybody could then appropriate them for any purpose.
That's not to say that the authors WOULDN'T give permission to include their works on the "Calonsound Youtube channel"; they very well might be okay with it. I'm just saying that many Calontir standards weren't written by Calontiri, and those authors might take a different view of this project.
Having said that, I'm sure I still have email addresses of a lot of the authors of these songs, and would share those addresses with whoever was going to be working on getting permissions. (most addresses were found via google, and on public sites and sources)
