CHORUS.
O lovely Polly Stewart,
O charming Polly Stewart,
There's ne'er a flower that blooms in May,
That's half so fair as thou art.
The flower it blaws, it fades, it fa's,
And art can ne'er renew it;
But worth and truth eternal youth
Will gie to Polly Stewart.
May he, whase arms shall fauld thy charms,
Possess a leal and true heart;
To him be given to ken the heaven
He grasps in Polly Stewart.
O lovely, &c.
