I'm enjoying it quite a lot! There's one song on there I'd heard before, "Hey Men", which is on their greatest-hits compilation called "Collection". There's also a cover of "S.O.S." by ABBA (palindromic song by a palindromic band, wheeeee!)
And I just noticed that the S.O.S. cover is the third song I can think of off the top of my head in which SOS is played in Morse code (... --- ...), the other two being "Ordinary Day" by Great Big Sea, and "Radioactivity" by Kraftwerk as performed live on "Minimum-Maximum".
Anybody know any other songs with ... --- ...? Or for that matter any other songs that use Morse code effectively?
