I did this MIDI for my sister but slightly modified it. I can't exactly replicate the song because there are background melodies that are too fast for me to sequence.
Here it is.
The MIDI is designed to play using SGM soundfont. Playing it with a standard MIDI might not be the most pleasant way to hear the composition.
This is the MIDI designed for Microsoft GS although this is not the best quality:
