Dutch comedians have a tradition of impersonating existing well-known individuals.
Hans Teeuwen rather shows the existential (psychological) barriers between incompatible characters.
When these personalities try to interact it inevitably gets twisted and results in a mindfuck.

Most surprising are the extreme transitions Teeuwen makes.
He can be a tortured poetic soul seeking truth, turn into a sadistic drunk hooligan, morph into a mental retard and change back to the initial poet within one act leaving his audience flabbergasted.
In 2005 Hans Teeuwen retired from the cabaret to focus on other media and forms of art, especially movies.

In October 2006 he announced that he will return on stage, but now he’ll only be singing. He is going to sing old jazz songs (mostly songs of Frank Sinatra) and the show will be called: 'Hans Teeuwen Zingt Liedjes Die Door Anderen al Veel Eerder, Veel Vaker En Veel Beter Zijn Gezongen'. This would translate to: Hans Teeuwen sings songs that have been sung a lot earlier, a lot more often and a lot better by others.
