Leaning on the Unknown Caller

I've been trying to figure out what sounds so dog-gone familar about the instrumental bridge just before Edge's incredible guitar riff toward the end of Unknown Caller on U2's new album, No Line on the Horizon. I'm convinced the song is about prayer (see my older blog post and look up Jeremiah 33:3...and take another glance at All That You Can't Leave Behind's cover art). The instrumental bridge reminded me of other music I know, but I just couldn't place it...until this morning. There is an old hymn sung by many, many Christians called "Leaning on the Everlasting Arms." One of the verses is: "What have I to dread, what have I to fear, Leaning on the Everlasting Arms? I have blessed peace with my Lord so near, leaning on the Everlasting Arms." If you know the hymn, see if the bridge in Unknown Caller doesn't sound very similar. And, after all, what is prayer other than learning to lean on the Everlasting Arms?!
