He was on a musical cruise and died Wednesday night after a performance, according to his wife.

It does sound like his life ended while he was doing something he enjoyed.
Damn. He’ll be making music with Brad Delp again.
He had one of the best Fros ever!
Did he actually play on any of Boston’s records?
Their first two albums. He also played on Barry Goudreau’s album in 1980.
I can’t think of a more fitting way for a rock and roll drummer to go out.
And for a white guy, no less!
