But despite the band’s confidence in the track, releasing it turned out to be somewhat risky.
In Queen The Greatest episode 3, a new weekly YouTube documentary series of shorts celebrating the band’s 50th anniversary, an unearthed interview with Brian revealed his original thoughts on the track.
The guitarist said: “I do remember having a slight reservation about Killer Queen.”
Brian continued: “I remember thinking, ‘Are we trying to sell ourselves as something that’s become very light?’”
The video also contains footage from Swedish TV of Queen’s record promoter Eric Hall, who made sure to get the single out to radio stations.
In the short clip, Eric hands Killer Queen to a UK record producer who certainly shares his reservations surrounding the track.
He said: “I’ll have another listen to it, it’s not really a breakfast record. Bit much really first thing in the morning.”
Freddie said: “As the albums have progressed, our sort of songwriting has progressed and we sort of ventured into different areas. I like writing different songs. We don’t like to repeat the same formula.”
Killer Queen would go on to influence the name of the We Will Rock You musical’s villain, originally played by Sharon D Clarke.
While in 2018, 44 years after the song was originally released, the track was covered by 5 Seconds of Summer.
The new version not only marked the release of the Bohemian Rhapsody movie, but also introduced the song to another generation of fans.
Next week’s episode 4 of Queen The Greatest will cover Early Tours, including a surprising story from a press conference in Finland.
Queen and Adam Lambert were due to tour the UK and Europe this summer, however, the pandemic has seen those dates postponed to 2022.
Nevertheless, the band’s 50th anniversary celebrations continue, with the release of the new rhythm mobile game Queen Rock Tour as well.
Here’s hoping Brian and Roger have even more surprises up their sleeves for fans later on in the band’s golden jubilee.
