the title and author of which i cannot recall right now but the gist was that they were at an event where they were requested to accompany a singer on the piano with a well known tune and after the intro the singer started exactly a fifth out - to save embarrassment they shifted key at an opportune moment only for the singer to then jump a fifth out again and so on... turns out it's a neurological thing some folk have - it was in a chapter on perfect pitch i fink, will check the bookshelf later...
