There is currently a campaign to get Delirious to number 1 for Easter.
Whether you like these campaigns or not it's a great song with a peachy base line! I know I've sung it many times with a desire in my heart to be significant in God's purposes. Also the idea of a Christian worship song being played out to millions of people is pretty cool too.
If you do want to join in you can download the song for 69p here. But do it before Easter!
