Everybody was in complete shock in March 7th 2013 when BBC announced that Bonnie Tyler would represent the UK in Eurovision later that year. The secret was very well kept (the arrangement was made around Christmas 2012!), since no rumors with her name were rolling.
So... Bonnie Tyler. Everybody was expecting a rock song, right? At least a rock ballad? Maybe... Well... Nopes. Bonnie took to Malmö (Sweden) "Believe In Me", a pop country that landed in the mediocre 23th position, out of 26 contestants. Big ouch.
Bonus: also in 2013, a big international name showed up in Eurovision: Cascada, the German dance music trio made famous by hits like "Everytime we Touch" and "Evacuate the Dancefloor". Only the lead singer, Natalie, took the stage to perform "Glorious". Despite being an early favorite, they only got the 21st place. Well, better then Bonnie, right?
