It was on this day back in 1970 the very influential Crosby Stills Nash & Young reached No.1 on the US album charts with "Deja Vu". This album was a keynote of the times. Profound music that although timeless in itself contains lyrics that are very distinctively 1970. It didn't get much better then this.
