As per on his social media page Phil Campbell and the Bastard Sons:
It is with great sadness that we announce the passing of our beloved father, Philip Anthony Campbell, who passed away peacefully last night following a long and courageous battle in intensive care after a complex major operation.
Phil was a devoted husband, a wonderful father, and a proud and loving grandfather, known affectionately as “Bampi.” He was deeply loved by all who knew him and will be missed immensely. His legacy, music and the memories he created with so many will live on forever.
We kindly ask that our family’s privacy is respected during this incredibly difficult time.
