I never really think of the 1980s as having such an unmistakeable look, but here it is: a sort of flamboyant, sugary Art Deco. It may be tacky, but damn, it sure is fun.
Wang Chung is underrated, in my opinion. Starting with 1983’s Points on the Curve, they put out several catchy, sophisticated pop albums. I hated them in 1987, of course, and would have been going on Space Mountain over and over again when the music started. That’s what I did at my grad nite in 1990.
Check out pre-“My Prerogative” Bobby Brown! It’s hard to think that at one time he was a somewhat normal guy with a more than tenuous grasp of reality and common sense.
See a whole lot more grad nite material at the ultimate old school Disneyland source, Vintage Disneyland Tickets.

Have occasionally looked for a band listing for Grad Nite 1987; my first ever venture to DL via 8 hours on a Charter Bus, one-way. Totally forgot about Bobby Brown being on the ticket. Thanks for the flashback.
