NEW YORK (Reuters) - Three country artists who performed at the Las Vegas festival that became the bloody setting of America's deadliest mass shooting reunited (Jan 29 morning, Singapore) on stage at the Grammy Awards.

Brothers Osborne, Eric Church and Maren Morris all performed at the Route 91 country music festival before gunman Stephen Paddock, 64, fired into the crowd on Oct 1, killing 58 people and injuring hundreds more. Paddock also killed himself.

On Sunday, the singers performed a haunting version of Eric Clapton's ballad Tears In Heaven, seated side by side in front of a backdrop lit up with the names of the victims.

"(We) are here to honour the memory of the beautiful music-loving souls all so cruelly taken from us," said Morris, paying tribute to not only the victims of the Las Vegas shooting but also the 22 people killed when a suicide bomb was detonated at an Ariana Grande concert in Manchester in May.

The tribute prompted a wave of appreciation on social media, including from gun control advocates.
