Yes, that's not the incorrect title

Many people had the British prog rock group Yes's best-known album on their walls for years - it was the thing do do for a while, back in the day - so you'd think there would be no confusion over it's title. However that does seem to be the case, where many are suprised to find what they had been calling "Tales from the Topographic Ocean" all along is in fact titled "Tales from Topographic Oceans".

Released in 1973, this was the sixth album from Yes and was based around lead vocalist Jon Andersons interpretation of a footnote in Autobiography of a Yogi (1946) by Paramahansa Yogananda. 

Searching today throws up many references to the "incorrect" title. Even the Yes official Facebook page gets it wrong.

Progressive rock masterpiece

Although it received mixed reviews on its release, the album went on to become a great success and has come to symbolise the genre's long song and concept format. It was the first UK album to achieve gold certification before it was actually released, i.e. on pre-sales alone.
