Any advice for editing audio captured from live performance?

I have a couple of concerts that I have recorded with my MiniDisc and transfered into my computer as .wav files. Does anyone have any tips for editing concerts? Iā€™m trying to minimize the audience noise (especially those assholes who drank too much and were yelling through all the music), and maximize the band.

Thanks for the help! :confused:

Also GoldWave. That is a good package for editing WAVs.
