I think it's like music for the sake of music, and a lot of the words stem from liking music a lot, wanting to be a good band and having a good sense of humour, and living in a situation where we're free to pretty much do what we want.
There are but two places where all go after death, white and black, rich and poor; those places are Heaven and Hell. Heaven is a place made for those, who are born again, and who love God, and it is a place where they will be happy for ever.
