John "Sib" Hashian, who played the drums on arena-rock group Boston's first two albums, has died at 67, TMZ and The Associated Press report.
His son Adam, who confirmed his death to TMZ, said Hashian was playing a set on a Legends of Rock Cruise when he collapsed Wednesday night. He did not provide the cause of death.
The cruise began last Saturday in Miami and was scheduled to make stops in the Bahamas and Puerto Rico. It's not clear how his death will impact the rest of the voyage.
