Random network questions

Why is every great american bash except the one's from 85, 86, and 87 included?

Why do they dub over Demolition's theme music?

​1)  Because those shows predate the PPV era for WCW.  They only exist as one hour edited home video releases and random matches shown on WCW programming at the time.
2)  Because they suck and don't want to pay Rick Derringer a penny more than they have to.  Not that I blame them for trying to save money wherever possible, but it's annoying as a fan.  ​
