I am looking for a tune called "Cuckoo Song".

I have it recorded by Mike Oldfield on his "the complete Mike Oldfield" double CD from 1985 - there it says "traditional".

I did not find the tune on the Digitrad or in the forum, also no results on the ABC tune finder (there are some titles containing the word "Cuckoo" - but none of them is the one I am looking for).
The tune sounds (in parts) like a (big surprise!) cuckoo calling...

Unfortunately I am very very untalented in writing down music from listening to it - so I'd be very glad if someone could provide it (ABC will do)

Thanks in advance.
