A band called AJR was featured on the channel, choosing a few of their favorite Beach Boys songs with some between-song commentary. Never heard of them and the show itself was way too short but it's nice to hear some actual DJ programming on the channel, which normally seems to just be the catalog on shuffle. They picked Sloop John B, Wouldn't It Be Nice, and Surfers Rule and then ended with their own version of Darlin' which sounded pretty good, reminded me of Nate Ruess's version from the Brian Wilson and Friends concert DVD.
So if it's the same version (and I suspect it is), the AJR version of "Darlin'" was actually released on Mike Love's
Unleash The Love album. And now don't quote me on this, but I feel like I remember seeing that Mike actually does feature on that track vocally or instrumentally, which makes its inclusion on his album a bit odd.
