Any way to remive the vocals from a song?

Saint

Basically I need to make an instrumental version of a little-known song for a performance in two days. Is there and possible way to easily remove the vocals from the mix of a song using free software? If not I could just record my own track, but this would be much better.

Yup.

Get Audacity, and then read this.

edit: kinda beat'd, but my link offers even more info and options, in case the OP needs it.

This works out great because I already have audacity, you H/A dudes are the greatest!
