The parade pieces I have feverishly been trying to memorize in lieu of carrying music in the parade:

Tonight from West Side Story

The Edge of Glory by Lady Gaga

Give Me Everything (Tonight) by Pitbull

Simple Hymn, which features melodies from Battle Hymn of the Republic & Simple Gifts

And a few extras for staying warm in our "downtime":

The Star Spangled Banner (No Inauguration is complete without it!)

Washington Post (the epitome* of parade tunes)

Mendelssohn's Wedding March (hint, hint)

*Use of the word "epitome" is credited to Mrs. Gorsuch for whom I learned it way back when.
