  We investigate the complex relationships between countries in the Eurovision
Song Contest, by recasting past voting data in terms of a dynamical network.
Despite the British tendency to feel distant from Europe, our analysis shows
that the U.K. is remarkably compatible, or 'in tune', with other European
countries. Equally surprising is our finding that some other core countries,
most notably France, are significantly 'out of tune' with the rest of Europe.
In addition, our analysis enables us to confirm a widely-held belief that there
are unofficial cliques of countries -- however these cliques are not always the
expected ones, nor can their existence be explained solely on the grounds of
geographical proximity. The complexity in this system emerges via the group
'self-assessment' process, and in the absence of any central controller. One
might therefore speculate that such complexity is representative of many
real-world situations in which groups of 'agents' establish their own
inter-relationships and hence ultimately decide their own fate. Possible
examples include groups of individuals, societies, political groups or even
governments.
