The Greatest Man That Ever Lived (Variations on a Shaker Hymn)

Clearly my favorite song right now. Clearly.

From Weezer's Red Album, "The Greatest Man Who Ever Lived" combines a traditional Shaker hymn with rock and rap in some sort of Queens-esque opera.

Which brings me to a request: I'm putting together a mix. I'm looking for contemporary music that integrates older songs, or the has elements that allude to an earlier era. Suggestions?
