CHANNEL PREMIERE: I know, I know. As channels go, this one is on radio, not TV – and only on satellite radio, at that. But this is the Beatles we’re talking about, so until I launch a sister website called Radio Worth Hearing (don’t hold your breath), I’m taking the time and space here to note the launch of the world’s first official Beatles 24-hour radio channel. It’s got special programs (including Chris Carter’s long-running FM radio staple “Breakfast with the Beatles”), vintage interview clips, rare outtakes, and lots more. The on-air promos have sounded terrific – and better than that, they’ve sounded smart. The ultimate number for a Sirius/XM channel devoted to the Beatles would, of course, be “number nine, number nine” – but that channel location already is taken by the decade-devoted channel ’90s on 9. So for The Beatles Channel, you have to tune your satellite radios to Channel 18. But numerology enthusiasts, such as Yoko Ono, will be happy to note the time this new channel is launching: 9:09 a.m. ET.  And if you don’t know the significance of “The One after 909,” or “number nine, number nine…,” then maybe this channel isn’t for you anyway. Or, come to think of it, maybe it’s for you most of all.
