I heard a sample of McCartney talking about the origins of Yesterday years ago on the radio and how he just woke up and there it was. Then a while later I was given a Naxos album following a Baroque music theme in my stuff on another continent and there's a theme from one of the songs on it that's eerily similar to yesterday except several hundred years older. Not quite Eric Carmen similar, but close to. But that's OK - all artists derive and there is no shame in it so long as you give credit where you can and from the sounds of things he wasn't even aware of the connection. The Naxos article is one of the very early ones and the labelling on it is terrible so I could never identify which labels applied to which CDs.
