Last year, his brother, bassist Mike Porcaro, also from TOTO, died after several years suffering from ELA. I was lucky enough to see TOTO during the last tour Mike played bass with them, some months after he left the tour because he though he had some injueries in his wrist, to discover he had ELA and had to left the band permanently and wait for the fatal end...
A family of genious, their father is also a very good percussionist and their other brother Steve Porcaro, is still playing keyboards with TOTO.
