In February 2007 Helena Vondráčková was confirmed as having accepted the invitation of Česká televize ( ČT ) , the Czech Republic 's Eurovision ( ESC ) sponsor , to compete in Eurosong 2007 , the national preliminary round for the Czech Republic in Eurovision 2007 , the Czech Republic making its ESC debut at Eurovision 2007 . Vondráčková was the only name which ČT confirmed as a Eurosong 2007 entrant prior to the official 15 February 2007 announcement of Eurosong 2007 entrants : this announcement stated that Vondráčková would be competing with a track from her 23 October 2006 album release '' Zastav Se ( ... A Poslouchej ) '' entitled " Samba " . Although the Eurosong 2007 final was not broadcast by ČT until 10 March 2007 the competing songs were made available for listening from the time of their announcement with voting - done by SMS - open from 23 February 2007 : around the last-named date ČT announced the disqualification of " Samba " citing the track had been recorded too far in advance to be considered as a possible entrant for Eurovision 2007 . Vondráčková , given the prerogative of competing in Eurosong 2007 with a more recent song , did submit the track " Ha ha ha " but soon withdrew from Eurosong 2007 citing her disenchantment with the winner being chosen by SMS voting
