One of the nice surprises of these last few weeks has been the chance to hear some new/old U2 music that’s rooted in their How to Dismantle an Atomic Bomb phase.  I already shared the link to “Country Mile.”  Here’s another song from the recent 20th anniversary reissue of HTDAAB: “Luckiest Man in the World.”  A quick glance at the comments reveals that it’s a “redone” version of an older, never-released song called “Mercy.”  That version is also worth checking out.
