I learned this song in the 1950's at school there was a verse that went like this

Last night as I lay on my pillow
Last night as I lay on my bed
Last night as I lay on my pillow
I dreamt that my bonny was dead was dead
bring back oh bring back oh bring back my bonny to me to me
Oh bring back Oh bring back Oh bring back my bonny to me.

anyone else heard this version it was the one taught in English Schools between 1955 and 1965.
