We have all made compilations of Beatles solo material, but within this large group, a smaller group has imagined taking some of this material and arranging it as The Beatles might have, had they recorded this material and issued it as "Beatles," the collective. There's actor Ethan Hawke's famous Black Album; Spencer Leigh's Finishing School, as well as any number of other efforts out there.    Then, there are the ones created by myself and my guest, Glenn Greenberg. You can find his list here, or else listen to the show and hear our choices and justifications, which are every bit as good as anything you listeners can come up with. See what you think - we can talk about this stuff endlessly!
