Between 1991 and 2013, Vermeulen following Luc Appermont had been the Flemish commentator for the Eurovision Song Contest. Due to unknown reasons in 1996, Vermeulen was unable to commentate on the 1996 Contest with Michel Follet and Johan Verstreken filling in, however returning to commentate on the 1997 Contest, since the 1998 Contest Vermeulen has co-commentated the event with other television presenters including Bart Peeters and Tom De Cock. Vermeulen had also commentated for VRT viewers at the 2005 Junior Eurovision Song Contest.
