The DT entries assume that 'Derwentwater's Farewell / Goodnight' (Roud 2616) are versions of 'Lord Derwentwater' (Roud 89, Child 208), which is not the case. They are unrelated, though on the same subject. Lesley Nelson (Giok's link above) makes the same incorrect assumption.

DRWNTFRW2.MID is Motherwell's 'Lord Derwentwater' tune (from A Blaikie, Paisley), while DRWNTFRW3.MID was noted by Charles Gamblin and Ralph Vaughan Williams from Mrs Goodyear of Axford, Hampshire, in August 1907 (as 'Lord Ellenwater'). Both midis are wrongly barred.
