Sadly, we are not kidding you. There is NO castle stage show this year for reasons unknown.. There is a small greeting-type little atmosphere show in that area but nothing to the effect of the regular special event show. Not sure if there is a Xmas CD for TDL at all, but I will visit the park tomorrow and find out. TDS is also NOT presenting a castle show at Waterfront Park... so last year's Minnie's Nutcracker may have been a "one-time/season" only show.
I spent the day at the park and there is NO Xmas cd. The music for the parade is your average traditional Xmas music. Similar to what the play at WDW's Xmas parade. No newly composed music. I very much doubt they will release a Xmas cd this year, especially since there is no major show at the castle.
However... they do perform a 12 minutes long Castle Lighting ceremony which is not a huge deal but is very pretty, featuring some of the classic characters in a Xmas musical moment.
