While I'm taking tunes down from Johnny Collins' Pedlar of Songs, here's his version of the tune (and as Dave sang on it and produced it, he's presumably OK with it). The verses are essentially the same tune as the chorus, except for the last verse, which alters on the last lines, and is included here.

Mick


Me/ fath-er gave I/ watch and chain the/ day that I left/ home
Me/ moth-er she cried/ bit-ter tears and/ begged me not to/ roam,
As I/ laid a-side me/ work-ing clothes, put/ on me tun-ic/ fine,
And I/ went to serve His/ Ma-jes-ty in the/ ranks of the sec-ond/ line.//

We stood/ fire in French-named/ pla-ces and we/ fought a-cross the /Seine,
But 'twas/ in the fields of/ Flan-ders I/ thought I'd met me/ end.
But the/ one that watch-es/ up above, or was it/ love that shield-ed/ me?
I ar-/rived home safe in/ Eng-land to/ take me bride to/ be.//
