This might sound suspicious, but I think someone should go onto Musescore, create a trial account, download the midi file of this song and upload it here. Unfortunately, I cannot do it, so I guess I'll just wait until someone fulfills this request. MCR's Mama is a great song, I love the way it changes tempo and all. :)

You are lucky that I am still a member of musescore for 1 year.
have fun with it ;-)

Omg thank you so much! I've always wanted to make a Wurlitzer 157 cover of this song but I could never do it without an accurate MIDI file, so you have just made someone's dreams come true! Have a great day, everyone who reads this comment! :DDD
