Anyway, they are performing the Skids song "The Saints are Coming" on Monday Night Football (on ESPN) live at the Superdome.
Here is a Time Magazine article: http://www.time.com/time/arts/article/0,8599,1534725,00.html?cnn=yes
The only problem is that the Superdome game is on Sept. 25th, NOT Sept. 18th. So which week are they performing? I assume the 25th (not the 18th like the article says), although we might want to check during both games, just to be sure.
