"Too modern"? What is
633 Squadron theme on Hyacinth then, the films were made in the same year? Or while we're at it, how is the BF1942 theme tune on PHL "non-modern"? Or the "Elk Hunt" from
The Last of the Mohicans on VB?
Zorba is at least based on a tune from 1949, which is still older than any of these.
Oh well, since Zorbas is based on a Cretan tune, we can always hope that Crete will get it instead
