According to the Dutch website Songfestivalwebblog.nl AVROTROS will not broadcast the 60th Anniversary Show in 2015. Yesterday it was rumored by a Belgian website that the 60th Anniversary Show will be produced by the BBC in London and will feature Graham Norton and Petra Mede as the hosts.
The Netherlands is one of a handful of countries to participate in all Eurovision formats, from the Eurovision Song Contest to Eurovision Young Dancers and the now defunct Eurovision Dance Contest. Back in 2005 for the 50th Anniversary, TROS did broadcast “Congratulations: 50 Years of the Eurovision Song Contest” along with 33 other countries.
