This is a very interesting article on the International House of Prayer:
The International House of Prayer set up shop on Sept. 19, 1999 and have missed nary a moment of exultation since. To keep up their relentless commitment to prayer, the church’s organizers schedule 25 bands each week in two-hour shifts.? Band members continue playing until the next band has taken the stage and is ready to take over. And IHOP staffers, many of whom spend at least 25 hours each week helping run the prayer ceremony, can elect to live close-by in a church-owned apartment complex.
