I got this picture disc as a birthday gift (thanks, Devlin and Mandy!) and it's awesome. Not the "listen to it multiple times" sort of awesome, but still.
Here's what you're getting: Some disco-type thing, then the audio of some wrestling matches and an interview then on side two some more narration and interviews (all in Japanese, of course) and then someone (I assume it is Tiger Mask) singing "I Can't Help Falling In Love With You" (In English) then more wrestling audio and disco and we're done.
Enjoy it!
Here's the link!
