Hysteria, in its colloquial use, describes a state of mind, one of unmanageable fear or emotional excesses. The fear is often caused by multiple events in one's past that involved some sort of severe conflict. But, this song is not about any of that stuff... It's a guy expressing the way he feels when his babe is near. "Hysteria" is the 1987 title track by British hard rock band Def Leppard from their multi-platinum album of the same name. The song peaked at number 10 on the Billboard Hot 100. Joe Elliot revealed that the title came from drummer Rick Allen. One of my fav Def Lep songs... Anyway, I decided to play this and sing as well... Remember, i am not a vocalist.
