MANILA -- Singer-actor Sonny Parsons, best known as a member of the OPM novelty macho group Hagibis in the '70s and '80s, passed on Sunday, May 10, at 61 years old.

His son Jeff Parsons told ABS-CBN News that his father succumbed to suspected heart attack due to heat stroke between 10 a.m. to 1 p.m. in Tayabas, Quezon while on a charity drive with his motorcycle club, Law Enforcers Riders Association of the Philippines (LERAP).

“We do not have complete details yet of his final moments," said the younger Parsons who, as of this writing, is en route with his family from the Parsons residence in Marikina to the Islamic Center in Taguig.

He said the family has yet to finalize Parsons’ burial arrangement following Muslim tradition.

"He was a datu and we will see how to carry out his wish to be cremated," he said.

At the height of their success, Parsons and Hagibis churned out “Katawan,” “Legs” and other hit songs extolling Pinoy virility.

Parsons also transformed himself as an an action lead star in the '90s.

He was elected councilor of Marikina in the late '90s.

Parsons last performed with Hagibis at the Philippine Arena concert of Imelda Papin and was slated to tour Australia this year.
