But I.canna forget others, gi'en I would.

When I'm singing I maun have a theatre i' which to appear.

And I canna fill that always by mysel'.

I maun gae frae place to place, and in the weeks of the year when I'm no appearing there maun be others, else the theatre will no mak' siller enough for its owners to keep it open.
And then, let's gie a thought to just the matter of my performance.
There must be an orchestra.

It maun play wi' me; it maun be able to accompany me.
