The song is one of the more controversial entries in Contest history , as it is the first to send the entire event up . The chorus , for example , features the nonsense lyrics of : '' Boom boom boomerang , snadderydang '' '' Kangaroo , boogaloo , didgeridoo '' '' Ding dong , sing the song , hear the guitar twang '' '' Kojak , hijack , me and you '' The performance is also memorable , as the band featured four male singers wearing cream suits and red shirts . During the performance , the men would turn their backs to the audience at various points , revealing a costume which looked like the front of a tuxedo , complete with a fake face . A performance like this had not previously been seen at the Contest , although it would not be the last time that Austria would be represented so irreverently , with Alf Poier doing similar at the 2003 Contest with " Weil der Mensch zählt "
