Hope it is not extremely off-topic for I have no idea where to ask else...
Listening to Yellow Submarine song my wife pointed that it sounds off-tune. I never thought of this (my ears are not as well trained), but listening now attentively, I found that it really is so, but not during the chorus. The chorus sounds perfect (?)
So the questions are:
- is it really slightly off-tune (not just impression or problem of digitizing old record);
- if yes, then is there any (semi-)official comment on this (simply scenic effect?) - I browsed wiki article but nothing of the kind is mentioned.
