Create and embed an RSS feed on my site (dodd)

We have an existing PHP site with a MySQL database - [login to view URL] (hosted on [login to view URL]) We would like an RSS feed of our blog to be displayed in the sidebar in place of the "Read our blog" image. This file can be found in /layouts/doddington/[login to view URL] The blog feed URL is [login to view URL] We would like the feed to be styled nicely to fit with the site, so perhaps the title can be a bar and be orange - play around with it and see what you can do. Obviously it needs to be thin enough to sit in the sidebar without pushing content out. Thanks.
