Sib Hashian, best known as the drummer of Boston, died Wednesday after collapsing on stage during a show on a cruise ship. He was 68.

According to a report from TMZ, Hashian collapsed in the middle of a set on the Legends of Rock Cruise. CPR was performed and a defibrillator was used but Hashian was not resuscitated.

Hashian, born John Thomas Hashian on August 17, 1949 was the replacement drummer for Boston’s original drummer, Jim Masdea. He can be heard on Boston’s self-titled debut album as well as the follow-up album. He left the band before the release of their Third Stage album.

In addition to his time with Boston, Hashian also worked with Barry Goudreau (another former member of Boston).

Hashian’s daughter, Lauren, has been in a relationship with Dwayne “The Rock” Johnson since 2007.  The two have a daughter together.

Johnson paid tribute to Hashian on Instagram calling Sib his “second dad.”

Rest In Peace & Love to my second dad Sib Hashian. Don’t know why things have to happen the way they do sometimes. When loved ones leave us so suddenly without having a chance to say goodbye. Perhaps the lesson here is the reminder to live our lives as full and as present as we possibly can, because we just never know what’s around the corner. What a full and exciting life this man lived. What an amazing family he created, loved, watched over and protected. Being on stage, in front of adoring fans, friends and family. Keeping the beat one last time. Your passing in this manner is extremely poetic and somehow beautiful. Thank you for the many life lessons you’ve taught over the years. Grateful. We love you Sib. We miss you. Yhmwitcoltroml. “Hasan burgers” for everyone in heaven.
