In 1979 Fleetwood Mac released an album entitled Tusk, in which the title song reached 8th in the US charts, 6th in the UK and 3rd in Canada and Australia. It is one of my favorites. The marching band of the University of Southern California performed with Fleetwood Mac in the song, and ever since, the USC band plays Tusk at every football game.
This is a video taken at the field level during a performance a few years ago. In the middle of the song they rush about, finally forming the letters USC.
This is the official Fleetwood Mac song video from 1979, made at Dodger Stadium in Los Angeles. The USC band shows up about a minute and a half into the video. In those days they wore the most Godawful ugly uniforms.
A bit of trivia: Tusk is also played by the University of Alabama marching band at every home football game. Know why? The university is located in the city of Tuscaloosa, Alabama. 😀
