If you get a music notation software programme, like Noteworthy , you can find the midi file and then load it into the programme, see the dots on the screen or print it out. Noteworthy allows you to print it even though you can download the programme for free. Most other free download demos don't let you do that. Noteworthy is cheap to buy anyway and good for most basic purposes, including transposing from one key to another.
Coincidentally, I just played Donkey Serenade a couple of days ago on my player piano i.e with the piano roll, not actually played as in "I know how to play it".
