In the mid-1980s, together with his colleague Günter Brödl he developed his alter ego Dr. Kurt Ostbahn, an excessive personality with an intense stage presence, which turned out to be very successful.

The name was created in the mid-1970s, when Günter Brödl was asked during a radio show what American musicians like Southside Johnny & the Asbury Jukes would call themselves if they were from Vienna.

After Günter Brödl died unexpectedly in 2000, Dr. Kurt Ostbahn went on a final commemoration tour and then announced in December 2003 that he would let his alter ego retire.

In 2006 he was on tour with the Kurdish singer Sivan Perwer presenting World music and together with the Xtra Combo Resetarits interpreted a wild mixture of Croatian Folk music, Wienerlieder (traditional Viennese ballads), Jazz and Blues as Stubnblues.

Resetarits was a human rights activist and one of the founders of the humanitarian organisations Asyl in Not and SOS Mitmensch.
