What song is often played at Memorial Day events?

Usually patriotic / military songs are used on Memorial Day since this day honors those that have died fighting for our country. Songs like:

'I'm proud to be an American' by Lee Greenwood.

The Battle Hymn of the Republic

America the Beautiful

My Country Tis of Thee

The Star Spangled Banner (but this is a tough song to sing)

Taps played by a bugler if the ceremony is at a war memorial or cemetary.
