One very obscure song

The movie Vanishing Point is one of my favorites though most likely not everyone's cup of tea. At roughly ten minutes into the movie a song places at Kowalski drives his Challenger into a the parking lot of a biker bar. I cannot, for the life of me, figure out what that song is. It's not on the soundtrack. As far as I'm able to tell it's not listed in the end credits as a song played. Midomi can't even figure out what or who it is. Worse still the only lyrics that can be heard clearly come up with just one hit on Google - and that hit is someone trying to figure out the song name!Mystery lyrics: "Oh, Lord, won't you help me to find myself a place to pray?"Singer? No idea. Male singer with a few background singers. I have a sneaking suspicion that Delaney, Bonnie and Friends preformed the song but the name and whereabouts today remain totally unknown.Any ideas?On a related note I think the drive in my Apple TV is going. I'm going to have to look up how it may be possible to break into the device and replace the HD with a solid state drive, if that is even possible. Or I may have to replace the Apple TV with a Mac mini with a solid state drive but I don't really want to do that (though it would combine the DVD player and Apple TV functions into one device - that is a plus).
