I am working on creating a website for a band. They want to have a simple blog/journal on their site. They would like to have the most recent post by each member display on the main page. Categories, comments, pingbacks etc are not important. I would like to find a simple blog software that would integrate well with other php apps on the site, mainly a photo gallery and a mailing list manager. What do I mean by integrate? I mean I would like to find a blog that I can hack a new authentication method onto so that the band members would only have one username each to sign on to use the blog, gallery or mailing list.

I have used other blog systems before (MT, WordPress) and they are great, but seem too complex to hack a new authentication method onto.

I also am not interested in using a full CMS because it seems too complex and has too many features that are not needed for a simple band website.
