The second UK single from 'Innuendo' was the first in America, a wise choice as the band needed to prove to American audiences they could still rock (something which had dogged their reputation Stateside since the lacklustre response to the 'Hot Space' album). And they really could still rock - with the thumping 'Headlong' climbing to an impressive number fourteen in the UK and scoring big throughout Europe, if not performing as well as was hoped in America.

The video was directed once again by the Torpedo Twins, Rudi Dolezal and Hannes Rossacher. By this point, the band and those close to them knew that Freddie was on borrowed time, and that they would never again perform live as a fourpiece. However, it was felt important to maintain the perception that they could still tour when they were ready to do so, and the performance footage filmed in Metropolis Recording Studios in London (where the band recorded much of 'Innuendo') is startling energetic considering the seriousness of Freddie's condition. He may have looked slightly frailer than in previous years, but he was still darting around as he had always done.

The second day of filming was spent in the control room and relaxation suite in the studio, as the band played around for the camera. Again, Freddie seemed surprisingly energetic, and was certainly enjoying the experience, perhaps knowing all too well that it would never happen again, as his final two video shoots were intensely gruelling for him physically.

The single was an average selling hit, and due to the inability to perform the song live (which the band had always been reluctant to do anyway) the video recieved a fair amount of airplay, and made its home video debut on 'Greatest Flix II' in 1991, and also featured on the American counterpart 'Classic Queen'. Keen eared fans may note that the video features a unique guitar solo, not included on any other released version of the song!
