Tusk

It grew from a rehearsal riff Buckingham used at soundchecks, which carried the working title Stage Riff. Fleetwood suggested using it as the title track. Buckingham wanted a hypnotic drum feel and the producers made a loop from a 15-second section of tape, sped up with a variable speed oscillator. The band also tried found sounds, including a Kleenex box, and the engineer Hernan Rojas recorded Chilean profanities that ended up in the track. Buckingham said the title had no particular meaning.

Fleetwood wanted a marching band after hearing a local brass band in Barfleur, and the University of Southern California's Trojan Marching Band, 112 members strong, was recorded in Dodger Stadium. John McVie was in Tahiti at the time and appears in the video as a cardboard cutout. The single reached number 8 in the US, 6 in the UK, 5 in Canada and 3 in Australia. Record Mirror's Alan Jones noted it was the largest ensemble ever to chart in Britain.

Marcello Carlin of Uncut called it the most avant-garde hit single of 1979. On the Tusk Tour Christine McVie played accordion. The Trojan band joined Fleetwood Mac at the Forum in Los Angeles and for the concert recorded for The Dance.
