I just read this article from The Sydney Morning Herald:
Man killed for singing Sinatra off-key
A 25-year-old Filipino man has been stabbed dead for singing a Frank Sinatra classic out of tune during a birthday party.
Police officer Noel Albis said the victim, Casimiro Lagugad, was asked to sing Sinatra’s popular song My Way during the party in the Manila suburban city of Caloocan on Sunday.
“Witnesses said the suspect, Julio Tugas, 48, one of the guests and a neighbour of the victim, got irked because Lagugad was singing out of tune,” Officer Albis said.
“Tugas suddenly attacked the victim and stabbed him in the neck,” he added.
Guests rushed Mr Lagugad to the hospital, but he died while being treated.
In my opinion, singing in tune is no easy task. If the assailant felt he could sing the song better, perhaps he should have taken a stab at it.
