Oh yeah, and the Dazz Band and New Edition were also at the park. I've never heard of that Dazz Band song that's mentioned in the advertisement either. Their biggest hit was the Grammy winning song, "Let It Whip," which hit #5 on the Billboard chart and #1 on the R & B chart. And just FYI.....New Edition's "Cool It Now" reached #4 on the Billboard chart and #1 on the R & B charts.
Making it's debut at the park that year, was the Country Bear Jamboree Christmas show and there was also a new film in the Circle Vision Theater. Check out this post over at Vintage Disneyland Tickets for the park brochure from that same Thanksgiving weekend. It includes ticket prices and additional entertainment information!
