Help to identify a (copyrighted) edition of Scarborough Fair

[Choralia]

One of my "virtual pupils" provided me with a (probably illegal) scan of a SSAA, a cappella arrangement of "Scarborough Fair":

I tried to locate the name of the publisher or of the arranger in order to lawfully obtain a copy, without success. Can anyone help to identify it?

The only thing I can tell you for sure is that it appears to have been done in Sibelius. Might narrow down the possible list a bit.
