Chris De Burgh - Lady In Red: The inspiration for this post. Not a nice guy - check out "personal life" on his Wikipedia page. What a dick.
Boys II Men - Bended Knee: Pretty much the gold standard for slow jams at the time. Now usually heard at the NH State Liquor Store.
Richard Marx - Endless Summer Nights: More of a feel good 80s song but I bet this was played at least once at a dance.
Bon Jovi - Always: This song wins the Cal Ripken award. Played at every single dance.
Bryan Adams - (Everything I do) I do it for you: Really cheap song.
Led Zeppelin - Stairway to Heaven: No comment necessary other than your night is over after this.
Any others? Let us know...
