I found myself groovin' out to this song when I played Kirby 64 the other day. I created this little rendition in about 3 hours, so it would be one of the shortest, work-time-wise, that I've done.
Update: Tidied up the bass a bit by fixing some wrong notes and improving expressiveness.

Update again: Changed a lot of things, including:
* tempo up a bit
* changed bass drum sound
* bass is more expressive
* added brass parts

Update again!
* Corrected some notes in bass line
* Adjusted balance
* Additions to brass parts
