Witty, tonguetwisting singers with an often satirical bite in their texts,, but just as likely to descend into hysterical silliness. I would think every country has such a national icon. In Norway, his name is Øystein Sunde, unchallenged for the last 40 years. Who has that honour in your country? And as for Americans, do you have any present day challengers to Lehrer's legendary, but somewhat hoary status?
