It's a never-ending process, it seems, collecting all the tidbits. Here's a Rehearsal video story I missed early - look for Ryan at 1:04.

I also uploaded all of the songs as they were sung at the San Francisco City Hall Inauguration sendoff concert. So, for your enjoyment:

America the Beautiful

An American Hymn

Hymn to Freedom

An Exhortation

Give Us Hope

I Hear America Singing
