Actually yes I had heard it - but didn't know it by title.

I grew up listening to a few Beatles albums from my parent's record collection - but when I got older and got into different kinds of music and started to realise what I really liked, I left the Beatles behind, so there were a couple of their albums I hadn't heard.

While I enjoy their music and relate to their influence in so many artists' work, I dont have any active interest in it nowadays.

Hence my lack of knowledge on this subject!
