Correction: January 28, 2020

In my post "Early 1970," about the beginning of the Beatles' breakup fifty years ago, I said that the singles-compilation LP The Beatles Again, later re-titled Hey Jude, was released in late January 1970. It was in fact released in February 1970.  The error stemmed from the fact that it was released on February 26, 1970, a Thursday, though I thought it was released a month to the day earlier because January 26, 1970 was a Monday, Monday being the standard day of the week for new record releases in the United States at the time.  The error, which I regret, has been corrected in the original post.
