How incredibly cool would it be if they'd just release a CD or double CD full of unreleased Beach Boys songs? And I'm not talking about stereo mixes, alternate takes, live tracks or binaural mixes or any of that stuff, but songs that have never been released in any form. There are so many of that that it shouldn't be too hard to fill one or two CDs with decent material.
It would be cool, but it would have to go through the whole vote/veto process with Carl's Estate, Brian/Melinda, Al, Mike, and whoever at Brother Records wants to speak for Dennis. There's also several legal matters that possibly keep things like this from happening as well.
