When USC plays Stanford, the bands usually design their half time shows so as to insult the other school. In a game during the 1980’s—I believe it was 1983 or 1985—the USC Trojan Marching Band concluded its half time show with a re-enactment of The Play—complete with the proper football uniforms and Trojan bandsmen dressed in Stanford Band uniforms. The real Stanford Band members were obviously not amused.
And if I recall correctly, all of the football jerseys had Elway's #7 on them.
OH! And I loved how the USC announcer would introduce the Stanford band onto the field:
“Please welcome the band representing Leland B. Stanford... ... ... JUNIOR University!”
