Watch magic happen when Annie Lenox and David Bowie sing together 'Under Pressure' in 1992.

Be prepared to watch a precious moment of music history. In 1992, Bowie and Lennox performed "Under Pressure" at a tribute concert for Freddie Mercury who had passed away the year before. Bowie and Mercury had originally released the duet a decade prior.  The performance of the song at a concert in London was pure magic.

Annie Lennox penned a touching tribute to David Bowie on her official Facebook page.

"Like a gazillion other people, I feel stunned by the news that David Bowie has departed this earth," the Eurythmics singer wrote in a message accompanied by a photo of the star during his Aladdin Sane-era, wearing the signature red lightning bolt on his face. "At the loss of someone who has impacted and influenced your life, you can hardly begin to measure the shape of what’s left behind. Our personal and collective inner landscape has shifted and we're trying to come to terms with it."
