Lady Gaga, Céline Dion, John Legend and Andrea Bocelli perform spine-tingling song together

Over the weekend, an eye-wateringly impressive line-up of global stars came together in a live-streamed charity concert, One World: Together at Home.

The special one-time event - which was organised by the Global Citizen movement (which campaigns against poverty worldwide), the World Health Organisation (WHO) and Lady Gaga - aimed to celebrate community health workers and generate funding to eliminate COVID-19.

Featuring appearances from some of the biggest names in entertainment, Céline Dion, Andrea Bocelli, John Legend, Lady Gaga, and world-renowned concert pianist Lang Lang stole the show with their grand finale.

Performing Dion and Bocelli's 1999 hit duet 'The Prayer' together from their homes, the quartet brought life to the magical song with their spine-tingling four-part harmonies.

The Prayer - which was originally recorded by Dion and Bocelli in two separate solo versions for the 1998 movie Quest for Camelot - was then released in 1999 as an airplay single.

It went on to receive an Academy Award for best original song in 1999, and won the Grammy Award for best pop collaboration with vocals in 2000.
