Rehearsals have been underway today (May 28) in Oslo for the Eurovision Song Contest in Oslo on Saturday (May 29).

After two semi-finals, 25 countries have gone through to compete in the contest in the Norwegian capital, which will be screened across Europe.

Ireland's Niamh Kavanagh - who won Eurovision for Ireland in 1993 - was one of the 10 qualifiers from the second semi-final yesterday to be voted through by the public. But Anna Bergendahl missed out.

France, Germany, Spain, the U.K. and last year's winners Norway all had an automatic place in the final.

The U.K.'s entry is teenager is Josh Dubovie, who will perform "That Sounds Good to Me," written and produced by Pete Waterman and Mike Stock.

Viewers vote by phone but cannot vote for their country's entry. The scoring is based on the combined public vote and the points awarded by a national judging panel.

The show will have an estimated 124 million viewers. But financial constraints among public broadcasters means that its budget has shrunk and four countries have dropped out.

NRK, the broadcaster from host nation and last year's winner Norway, sold its rights to the World Cup to finance Eurovision and indicated it would not have the cash to stage it next year if Norway wins again. Corporate sponsors Telenor and Norwegian Air came on board to help with costs this year.

A smaller country such as Azerbaijan might also struggle with the burden of staging Eurovision, but its entry from Safura is 9/4 favorite with bookmakers.

Germany's entry, "Satellite," by Lena is second favorite at 3/1.

But there has been some concern among Germans about her decision to sing in English - and U.K. pop act Kate Nash may feel a bit aggrieved if Lena does go on to win judging by this clip - especially as Nash's second album has not performed well so far. But even if there are similarities, at least both acts are signed to Universal labels.

Lena's set "My Cassette Player" (USFO) is currently at No. 8 on Billboard's pan-European albums survey.
