One of my MOST favorite songs is "Sing to the King" by Billy Foote. There's an energy with this song that just gets my hands up and the rest of me swaying. It comes from an old hymn called "Sing We the King" from 1910 (at least the first verse). The awesome chorus was added and it has been recorded by Passion, Hillsong and, most recently, Sandy Patti.
The chorus lyrics are:
Come let us sing a song - A song declaring we belong to Jesus -
He's all we need.
Lift up a song of praise - Sing now with voices raised to Jesus -
Sing to the King!
