The outstanding characteristic of the WISE GUYS is that nearly all of their repertoire consists of their own works. Their catchy and varied popsongs with German lyrics are always of top quality, whether they are witty, cheeky or melancholy. Their talents in acting and repartee, their entertaining presentations and natural ease on the stage are contributory factors to their great success, which has led to their being one of the best-known a cappella groups in Germany.
