You know who the has beens are by who is pulling their music.
Anything to be relevant and to get mentioned in the press.
I actually have nothing to say that Barbra has even expressed this... that is why I framed the post as a rumor. There have also been rumors that Barry Manilow and The Foo Fighters as well as Bruce Springsteen were pulling theirs. I think much of this is a pressure campaign on the part of bad actors on Twitter. The goal is to shame musicians, especially those with known left-wing leanings, to jump on the bandwagon.
