It's funny you asked this because I was thinking the other day that we haven't done any "Fun With Covers" for quite a while. We'd all participate, but then Wasanelder used to put them up on Youtube. They're still there if you want to take a look. On Youtube, just type in "Fun With Covers 1" or Fun Withe covers 2" and you'll see them. I think they go all the way up to "Fun With Covers 23". Here's a few links to them:
