Just to confirm that after a reply from John M. Croall, folk musician and J. T's Bairns former member - he did not write the song 'Culloden Moor'.

However, the PRS/MCPS database has mixed him up with another John Croall who is part credited with the song.

There are also dozens of trad. arrangements of songs and instrumentals recorded by J.T.s Bairns that are registered or part registered to the modern Mr. Croall, and as a non-PRS member I don't think he knew anything about them.

So it seems to be that the PRS computer system, has mixed the two parties up - given them the same code number and put an 'M' in the original Mr. Croall's name making them one in the same party when they are not.

Complicated isn't it? Based on the MCPS/PRS registration information I put John M. Croall on the credits of a youtube video, rather than just John Croall.

I might try publishers Universal Music and see if they have any info.
