Angela Rippon presents a guide to some of the Eurovision Song Contest's most disastrous moments. Including the kiss that ruined the chances of Danish singer Birthe Wilke.

The Eurovision Song Contest is an international song competition, organised annually by the European Broadcasting Union (EBU) and featuring participants representing primarily European countries. Each participating country submits an original song to be performed on live television and radio, transmitted to national broadcasters via the EBU's Eurovision and Euroradio networks, with competing countries then casting votes for the other countries' songs to determine the winner.
