Two thoughts

I use that extra comma, but never knew it had a name (I did know it tended to be more common among Brits). Turns out, it's called the Oxford comma. There are a lot more articles about it on Google. I've been thinking of switching my usage to using it only when it disambiguates something.

My old friend, Terry, wrote from out of the blue Monday and recommended The Mountain Goats (a band) to me. I downloaded some mp3s to tryout, but haven't...err...tried them yet. They do have a song called Color In Your Cheeks (Iowa City Trance Remix) , so that has to be a good thing.
