"A mole digging in a hole, digging up my soul now, going down, excavation." One must admire Bono's ability to rhyme "excavation" and "elevation" in this song and to use them almost interchangeably despite the fact that they mean opposite things. One is literally getting higher and one lower but who has time for such quibbles? Also, at last the humble mole is recognised for its lyrical properties. We're so easily distracted by flashier, less rodent-y creatures and meanwhile the mole is working away like an absolute trooper, digging through a rockstar's chest to get to the chewy soul inside.
