I made a list with the tax burden as total tax revenues as percentage of GDP in the countries participating in the Eurovision Song Contest 2012.

The data is from The Heritage Foundation Index of Economic Freedom 2012, OECD Tax Revenue statistics and from The World Bank.

The lowest tax burden has Azerbaijan (14,4%), Lithuania (20,9%) and Georgia (21,7%).
The highest tax burden has Belgium (43,8%), Sweden (45,8%) and Denmark (48,2%).

Here is my document TAX%OFGDPESC2012.
