TCM is showing a lot of MacDonald and Eddy films this month, and I am watching them. I think they are both very good....and Nelson Eddy could be very funny.....as could Jeanette MacDonald.
Although.....I have to say that my favorite JM film is the remake of Smilin' Through that she made with husband Gene Raymond (sugar daddy of Mr. Robert Stack in his early Hollywood days, some say).
