Yeah, they were pretty cool. Dude usually played a baritone sax though.
I never saw them live, but I saw Mark Sandman's previous band, Treat Her Right, a few times. And after Sandman dropped dead on stage in France, we had a show come through here billed as the "Morphine Orchestra" which consisted of the sax and drums from Morphine, plus most of the guys from Treat Her Right, and a few friends to fill things out. Sandman's bass was on a stand center stage, with a vase of roses. It was a really good show, and about 50 people showed up to see it.
Sandman liked to cultivate an image of mystery and danger, and he hinted at a dark past. For example, he claimed that there were some states that Morphine couldn't play in because he wasn't allowed in. But there were also reports that he was one of the nicest people you could ever hope to meet. I've got a friend in Boston who was moving into a new apartment, and had to be out of the old one a week before he could move into the new one. He happened to meet Sandman in a book store and they were chatting, and Mark offered to let the friend and his girlfriend stay at his place. So for a week, they slept in Sandman's bedroom while Mark slept on the sofa. And they had never met before.
