Jeri, I'm pretty sure that Chris Walshaws ABC homepage does offer some ABC to MIDI converters and might be worth looking at.The converter that I use the most was given to me by somebody from one of the music newsgroups who is the process of developing it and was given "on trust" - otherwise, I would share it with others.
If you post (or email me) the ABC for that tune, I will convert it and supply it in MIDI.
