As a followup to yesterday's post "MSN to host Live Earth concert series" it appears as though the series of concerts is going by the name SOS - Save Our Selves. While the url http://sos.msn.com/ looks to be where the music is actually heading, the placeholder homepage for the global event is already live at http://saveourselves.com/.
Save Our Selves (SOS) aims to connect people around the world with seven concerts on seven continents on 7/7/07, to create a global community with a single environmental vision and purpose.
From the various pages on the site, you can see that Live Earth Event, LLC is running the shows, though no mention is made of MSN yet.
Register now to be kept informed. Announcement later this week so we've heard.
Update:
Live Earth - Save Our Selves concert series announced
