Letters / Who were Joey and Hetty Robertson?

Sometime in the 1940s, or perhaps slightly earlier, Jane Saxby of Gloup wrote a poem Helyinagro. It was set to music by her relative Miss Reid Tait.

In the Reid Tait collection in the Shetland Archives there’s a fragment of a concert programme where the text of the poem appears.

At the concert it was recited or sung by ‘Miss Joey Robertson’. On the same occasion ‘Miss Hetty Robertson’ and Jim Scott recited other material.

Can anyone tell me who Joey and Hetty Robertson were, and thus roughly when the concert might have taken place? I’d be very grateful for information.
