This is a solid feature that makes good use of musical clips without having them be obtrusive to the flow of the story. The people interviewed give both color and expertise and the narration keeps everything moving together.
However, the transition between the first half on the history of music on cruises and the second half about the musicians of the Titanic is a bit forced. The listener might ask himself how the two are related. In order to fix this, the piece would have to be introduced in a way that made clear that the brief history was to provide context for the story of the Titanic musicians. This is a good piece to broadcast on the anniversary of the sinking of the Titanic but could seem out of place if not time pegged.
