WXRU is slated to go all Christmas from November 23 through December 25 - http://www.wzru.org/events.html
No online listen link was found though I could have very well overlooked one.
From the web site:
December 2008 "Christmas at Home" Sooner than you think it will be the Holiday season and we at WZRU are gearing up for yet another great Christmas music Program. WZRU invites you to participate in our "Christmas at Home" programming schedule, during which WZRU presents 50 years of easy holiday favorites. This year's schedule begins November 23rd and runs through December 25th. It has been a busy year with some changes. One thing that has not changed is our music format. Our signal is now heard in 25 counties. We have also installed generators to keep us on the air and bring valuable information to our listeners during weather related disasters. So, let is snow!
