Bulgarian song "Angel Si Ti" (Ангел си ти) performed by Miro will be presented at the Eurovision song contest semi-final in Oslo tonight, May 27 2010, an event which will be televised live by Bulgarian National Television (BNT) at 10pm Bulgarian time.

Reportedly, the morale of the Bulgarian delegation in Norway is "superb," BNT said, while Miro is in "excellent form". The last general rehearsal on May 26 apparently went "in a flawless" manner which is said to be vital for the international jury.

Tonight, only people can vote from countries that are not participating on the night – with tonight's contestants including performers from Latvia, Armenia, Israel, Denmark, Switzerland, Sweden, Azerbaijan, Ukraine, the Netherlands, Romania, Slovenia, Ireland, Cyprus, Croatia, Bulgaria and Turkey. But people in the United Kingdom will be eligible to vote. The Bulgarians are hoping that compatriots living in the UK would "mobilise" and "do their duty," the report said.

The outcome of the vote would be known at about midnight Bulgarian time.

The Eurovision Song Contest 2010 is the 55th annual Eurovision Song Contest event, and it will take place at the Telenor Arena, in Baerum, Norway, a suburb of Oslo. Norway won the right to host the tournament after Alexander Rybak's win at the 2009 Contest with "Fairytale".

It will be the third time Norway has hosted the contest, having previously done so in 1986 and 1996. The finals of this year's contest are on May 29.
