Perhaps I should have stated earlier which sheets I have copies of.
When the Cock Begins to Crow (cover only)
John Macraw, no cover and not original as it's dated 1908.
You Never Miss the Water, full copy Hopwood & Crew stock no1984.
Jim the carter Lad (full photocopy) Published by George Bell of Leeds.

I think those are the only Linn sheet music I have, but I probably have others on broadsides.
