Possibly the instrument is the problem:

The notes (SEDAR filing) were correct, but the publishing to the media off-key.
And now the typo is spreading, it is really a pity:

Well, the typo is obvious for the experts, so I just see the problem that POET is showing an unproffessional image.

But Mack, you are right, it seems that the right artist is missing.
Ah well, and sometimes... the composition is genious and the sound still seems out of tune. Modern classic...
