The campaign's official motto: "Make American Idiot Great Again."
The plan, so far, appears to be working. On Amazon in the U.K., "American Idiot" is currently the best-selling song.
"Us in the UK have a good record of protesting in this way," the campaign's founders, Keith Curle and Geoff Thomas, told The Washington Post. "We are the country who put Sex Pistols and Rage Against the Machine at No. 1 in the past."
Green Day's Billie Joe Armstrong wrote "American Idiot" in the throes of the Iraq War and the angst of post-9/11 America, which the song described as "an alien nation where everything isn't meant to be okay."
The titular track on the band's 2004 rock opera resonated with a generation of eyeliner-wearing, anti-establishment punks while at the same time playing ad nauseam on car radios in American suburbia, spending six weeks at No. 1 on Billboard's Top 100.
Trump is mostly avoiding London throughout the duration of the trip, where the protests will be most concentrated, The Associated Press reported.
A giant blimp depicting Trump as a baby holding an iPhone is also expected to greet him in London, should he get close enough to the protests to see it.
