Going off on a tangent after a debate with the Mrs about whether that Moldovan bloke was genuinely playing the saxophone, found this - "1999 Countries preferences to use backing tracks virtually leads to the abolition of orchestras. Live music became optional and all broadcasters since 1999 have declined to use an orchestra. In 2004, all live music was banned; even artists on stage were not allowed to play their instruments live, even if they explicitly voiced their wish to do so. This live music prohibition is still in place"
Had no idea they weren't allowed to play any instruments. Good to see that the spirit of Eurovision involves stamping out any hint of musical talent.
