What is the longest song written with words?

The longest song in the world (with Words) to many people is Free Bird, estimated between 14-16 minutes long. this may not be a long song compared to many other songs(without Words though), but it is very long...many people hate this song because it is so long...i think it is awesome.(listen to the vocals and there is sorta like a message it sends to you.)

In the world of Progressive Rock, there are many songs longer than this.

Green Carnation - Light of Day, Day of Darkness clocks in at an hour

Chris Butler - The Devils Glitch racks up 69 minutes

Plus many more 20 minute+ songs...
