The Beatles .....


…..someone please tell me why their music ( re-issues ) are always available to the public on the 9th day of the month ?

…….okay I guess that I wasn't clear in my question : If you look back, all of the Beatles music re-issues were all made available on the 9th day of that particular month. For instance, the 50 year anniversary re-issue of The Beatles White Album will be available on 11/09. So all Beatle fans …..why does their music become only available on the 9th day of the month ? Is it because of the '' that '' song ?

No rja it is not a trick question.
