There's lots of sites offering free MIDI files - some of those files are decent (often bootleg copies of purchased files), but a lot (most) of them are pretty bad. I've bought files from a few places, though some of the files for sale are as bad as anything you'll find for free (at least you get to hear samples before you buy, which is a good thing). I've had good luck with songgalaxy.com and a few other places, but my go-to site is yamahamusicsoft.com . You'll likely have to mess with program changes and such for the track to play the way you want on a non-Yamaha keyboard, but that's half the fun. Note that they've recently added a slew of "Premium songs" for more money, but the cheaper versions are actually (IMO) better - the Premium songs have a decidedly European flavor (a nice way of saying schmaltzy polka band sounding (-; )
