Several other versions have been posted but not the actual video so here it is.
"We Will Rock You" is a song written by Brian May and recorded and performed by Queen. One version was used as the opening track on their 1977 album News of the World. This version consists of a stamping-clapping beat, and a power chorus, being somewhat of an anthem. The stamping effects were created by the band overdubbed the sounds of themselves stamping and clapping many times and adding delay effects to create a sound like many people were participating. When performed live, this version is usually followed by "We Are the Champions", another of the album's hits, as they were both made to lead into each other. On the 45 of the song's original vinyl record release, the song was actually the flip side of "We Are the Champions" in England, however the American record company requested to put the two songs together as a "double A side" because American radio stations were playing them back to back. This is a reason why the songs are often paired on the radio and at sporting events, where they are frequently played. The songs are also paired back to back on the album, as they were designed to run together and they are still played together to this day on American classic rock radio stations. Queen also performed the song in another arrangement (known as the "fast version"), which featured a faster tempo and a full guitar, bass and drums backing track throughout. The band would often open their live sets in the late 1970s and early 1980s with this version, as captured on their 1979 Live Killers double album, on Queen Rock Montreal (2007), and on the Queen on Fire - Live at the Bowl album released in 2004.
