Just a thought from an old organist /choirmaster: my choir members say that a hymn is what you remember when you are lying on a guerney outside of the operating room. A praise song is what you recover to.
I have choir members who have recalled the hymns they sang in their minds while under the white sheet waiting for the operation in the cold waiting area. Think about it; HIS Eye IS ON THE SPARROW or LORD I LIFT YOUR NAME ON HIGH> I know what I would sing. When my dad died of cancer my family circle his bed and sang for the whole night. What did we sing? The good old hymns. Heely
