Sort of like Disney getting extended copyrights on their old stuff.
Every 20 years or so, they pull out a few old items in remastered format, and sell them during a short window of time.
The Disney stuff extends some 70 years (or more).

If the old music recordings gain prominence again, look for Cher and Babs to do more Farewell tours.
NOOOOOOOOOOOOOOOOO!
