A jobless man was shot dead by a security guard for singing out of tune in a Philippine karaoke bar, police said Thursday.

Romy Baligula, 29, was halfway through his song on Tuesday night in a bar in San Mateo town, east of Manila, when 43-year-old security guard Robilito Ortega yelled that he was out of tune.

As Baligula ignored his comments and continued singing, Ortega pulled out his revolver and shot him in the chest.

Senior Superintendent Felipe Rojas said Baligula died instantly.

The security guard was detained by an off-duty policeman shortly after the shooting.

Deaths and violence are not uncommon in Philippine karaoke bars.

The popular Frank Sinatra song "My Way" has been taken off many karaoke bars in Manila after it was found to be the cause of fights and even deaths when patrons sang out of tune.
