Football's relationship with jazz continued for some time. In 1972, drunken face-painted hordes wiped the nacho cheese off their mouths to sing along with Ella Fitzgerald's salute to the recently deceased Louis Armstrong. Finally, in 1976, they hired the first contemporary band to play. David Bowie, Stevie Wonder, and the Disco Duck were all too busy being relevant, so Up with People! played instead.
The remaining years were a desperate stretch that would dismay even a Browns fan. In 1978, the entertainment break between people catching balls was dogs catching Frisbees. In 1987, 91-year-old George Burns told jokes while Mickey Rooney danced with Mickey Mouse, squashing any rumors that they were the same Mickey all along. In 1989 they hired a goddamn Elvis impersonator. Not just any Elvis impersonator, either -- one who performed card tricks and called himself Elvis Presto.
Terrible even by late '80s Vegas standards.
The NFL hired its first mainstream contemporary pop act in 1991. The New Kids on the Block's set was kicked off by America's other teen heartthrob, George H.W. Bush. Although it wasn't exactly the glorious launch of a media institution, since most stations played the president's prepared statement on the Gulf War instead.
