Mark your calendars, set the clocks: Jon Solomon’s 23rd Annual 24-Hour Holiday Radio Show is coming soon! The marathon begins on Friday, December 24 at 6:00 PM ET and ends Saturday, December 25 at 6:00 PM ET.

It’s not Christmas without Jon’s annual holiday marathon. Seriously! From the absurd and bizarre to the beautiful and almost-kinda-holy, Jon’s show traverses the terrain of holiday music. No two marathons are alike, and perhaps that’s why listeners both near and far flock to the radio and/or webstream. So says Inside Jersey:

Forget the Bing Crosby-Nat King Cole-Mariah Carey loop that seems to air on every station in every mall – Solomon mixes covers of traditional hits with songs by bands from the region, recordings lost to attics and basements, and esoteric picks like “Mr. Russian, Please Don’t Shoot Down Santa’s Sleigh,” a Cold War-era number.

Which is not to be confused with “Can Santa Miss Those Missiles,” Solomon says.

You can RSVP for this show on Facebook.

Jon wants you to know that if you would like to make some requests, by all means get in touch.

The 2010 Xmas Playlist will be updated in real time.
