There are a couple of interesting things I've noticed about this album:
Firstly... it may have escape a lot of people's notice (I only noticed on closer inspection myself), but there is a "Secret" Poem/Lyric on the back cover - top left of the back cover mural, in the white area. A very light grey block of text for something titled: "The Deep Deep Sound"
And secondly.... not so much a mis-print, but rather a seeming lack of consensus about how to spell Mount Teidi...
...On my copy, the inside gatefold track-listing (which is the same for every national issue) gives the spelling as: "Mount Teide" - with an "E" at the end - but the labels on mine give the spelling as: "Mount Tedi" - with an "I" at the end.
This same discrepancy between cover and labels is also on the Swedish issue currently on site (See below), whereas it seems the German one is consistent with :"Teidi".
Having checked the issues of the single: "Family Man" taken from this album, which has Mount Teide/i as the B side, there is no consistent spelling there either, with different country's issues going for either of these spellings (See Mike Oldfied discography on 45cat).
