Fiddler Oliver Schroer's name was mentioned in the credits. The other musicians' names I didn't recognize.

Definitely a worthwhile series; I watched every episode on History Channel, and likely will watch it again if it comes round again. I spent time in Northern Manitoba, and also used to do lots of canoe tripping. The series rings true on both counts. I was particularly impressed with how they managed to keep the film crews out of the action and create the illusion that these people were all alone in the wilderness. (Actually, the film crew and doctor were all alone in the wilderness with them, but had communication with the outside world.)
