to get you started here are 2 interviews:
the first is during the 7800 tour
This is already promoting SWW, but they mention a few things about 7800
if you ever catch a bon jovi day on VH1 there are 2 pieces (one is ultimate albums about sww but it has stuff about 7800)
and another one- that I don't remember the name right now
they split before 7800 was written
here's a short clip
Tico: we all had girl problems, it was a very depreesing recrod
Doc: "you read the lyrics and you want to cry"
