Lyrics are accurate, and as in the book apart from the following minor corrections :

The second "verse" listed, which is repeated, is of course a chorus. Andy wrote "boat", not "ship", and also "it's feared IT'S gone down with all hands", not "she's".

Verse 2 starts "Oh and white were the wave-caps....", not "And it's white were the wave-caps"

In the interests of musical and historical accuracy, I know for an absolute fact that Andy would prefer that it be credited to "Andy M. Stewart" rather than "Andy Stewart" - that 1 initial makes a world of difference.
