Wow, could you imagine what it would be like to participate in corporate worship in song for 4 hours?
Back in the old days, fellowships used to do that. We would have all-night meetings, where people just slept on the floor if they got too tired. People with kids would bring them for an hour, then take them home to sleep and come back.
Often it would be centered on prayer for revival before a speaker came to town, or New Year repentance and renewal, or another specific concern. The OT had sackcloth repentance, where the whole city turned out. Charles Finney revivals involved more preaching, but were intense. IHOPS have mid-week long worship services. (Not the pancake houses.)
Long worship and prayer services are more widely accepted in Korea and Africa. (Pipe in, anyone else.) I think the Methodist camp meetings used to hold long services too... does anybody know?
Now we think we're too busy. Or dependent on a leader to hold services. Things are relatively comfortable, and Christian influence widely available, so we don't sense that pressing need to invest large blocks of time.
In contemporary churches, some worship team members practice and pray for an hour, then worship during two services -- that can add up to four hours of singing worship and prayer, depending on the church.
You might want to visit wteam practices, and offer to pray for them while they practice -- it's very nice to worship in a quieter, more flexible setting, where you're free to walk around.
The OP question for me, would be -- where are a few people who are so dedicated to prayer and the mighty work of God, that they will take initiative whether a pastor does or not.
I tend to find a large percentage of them in Charismatic churches, so when I feel desperate for that kind of spiritual support, I head toward a good Charismatic church. It is not just the size, but the intensity that matters. If you felt supernaturally oppressed, would a few people come round you and declare the power of God over that circumstance... take charge spiritually... people like that are needed, to keep good worship alive.
Worship ties in, but experience in spiritual life usually brings additional strength and discernment (hopefully)...determination to live out Christianity the way Jesus asked His disciples to. If you can find a few people that are willing to live like that, then go where they go... or create a worship service with them.
What, we still didn't answer your question? (-;
