I played a benefit the other night that was videotaped and we did a couple of tunes where I played some slide...it might be a week or so, but I will try to post something then.
Do a search with the keyword "slide" in the Tips & Clips section. Kirk's stuff is probably the best stuff there ... but there should be others. I have some at the link in my signature you are welcome to listen to ... just not as good.
THe first track is off the last Mr. Nasty album and has a bit of slide on it. The second track is one we've never finished up, no vox but the last 45 seconds or so there's abunch of slide.
