Though I haven't found (after a quick search) where KYKY in St. Louis, Missouri has ever made the Christmas radio station list, they do organize a Christmas concert each season.
This year's "The Y98 Mistletoe Show: An Acoustic Christmas
" concert will take place on Saturday, December 15th, 2012. This year's performers are Train, Alanis Morissette, Grace Potter & Tristan Prettyman!
Ticket details and prices are in the above hyperlink.
Now, if they would just air the concert over the air!
