Wee Willie Gray, and his leather wallet;
Peel a willow-wand, to be him boots and jacket:
The rose upon the briar will be him trouse and doublet,
The rose upon the briar will be him trouse and doublet!
Wee Willie Gray, and his leather wallet;
Twice a lily flower will be him sark and cravat;
Feathers of a flee wad feather up his bonnet,
Feathers of a flee wad feather up his bonnet.
