Oh man, I graduated high school in 1988. Right up my alley. Lots of good suggestions on here!
I'm not sure I saw these, so I'll add these in case they weren't on the list...
- Extreme Whole Hearted - Whitesnake Is this Love - Metallica Nothing Else Matters - Scorpions Still Loving You - Heart Alone - Dokken In My Dreams - Def Leppard Love Bites - Bon Jovi Wanted Dead Or Alive - Bad English When I See You Smile - Great White - Other songs were mentioned, but maybe not Lady Red Light, Rock Me, House of Broken Love - Not sure how far you want to go back - Bonnie Tyler Total Eclipse Of The Heart
Listen closely to Kix. Little know fact, the lead singer has a lisp and the band backs him up providing the "s's" where they can.
