X is for X files

Well come on, give me a break, how many song/tune titles are there begin with the letter X for my aplha ponty challenge?
Xanadau? I love where I am, but it sure ain't paradise.
There is a song about Xena Warrior Princess, but try as I might I could not persuade Lucy Lawless to fly over here at her own expense just so I could take one photo of her, and I am not near a DVD shop at this time of the morning to snap the box set.
So you will have to settle for the X files., and since Mulder and Scully are not available for the very same reasons as Lucy Lawless isn't, I fear a compromise had to be made.
