English Poetry - IF YOU KNOW THE ANSWER HELP PLEASE!

I'm studying the poem Summer Farm by Norman MacCaig in English class and I really need to know what year it was written or even published in?

It appears in "The poetry of Scotland: Gaelic, Scots, and English, 1380-1980" published in 1995 but I'm not sure that was the original publication. It doesn't show on a search as an individual publication but it could have been published within a collection of McCaig's work earlier.
