I'LL LAY YE DOON, LOVE

   O I'll lay ye doon, love, I'll treat ye decent
   I'll lay ye doon, love, I'll fill your can
   O I'll lay ye doon, love, I'll treat ye decent
   For surely he is an honest man

As I walked oot on a summer evenin'
Doon by the water and the pleasant strand
And as I was walkin, I heard them talkin'
Sayin', Surely he is an honest man

O I'll lay ye doon, love, I'll treat ye decent
   I'll lay ye doon, love, I'll fill your can
   O I'll lay ye doon, love, I'll treat ye decent
   For surely he is an honest man

I hae traveled far frae Inverney
Aye, and doon as far as Edinburgh toon
And it's I maun gae, love, and travel further
But when I come back, I will lay ye doon

O I'll lay ye doon, love, I'll treat ye decent
   I'll lay ye doon, love, I'll fill your can
   O I'll lay ye doon, love, I'll treat ye decent
   For surely he is an honest man

I maun leave ye noo, love, but I'll return
Tae ye my love and I'll tak' your hand,
Then no more I'll roam frae ye my love
Nae mair tae walk on a foreign strand.

O I'll lay ye doon, love, I'll treat ye decent
   I'll lay ye doon, love, I'll fill your can
   O I'll lay ye doon, love, I'll treat ye decent
   For surely he is an honest man
