Het nummer They Can't Stop the Spring waarmee Dervish in mei Ierland vertegenwoordigt in Helsinki op het Eurovisie Songfestival herinnert aan de door de Russen bruut gestopte Praagse Lente in 1968. Het haalt bijna letterlijk de woorden aan die de Tsjechische leider Alexander Dubcek sprak nadat binnengevallen Russische tanks destijds de bloemen vermorzelden die vredelievend protesterende studenten toegeworpen hadden: "They may crush the flowers, but they can't stop the Spring".
De Ierse inzending is geschreven door journalist/schrijver John Waters. Hij zegt erover ondermeer: "When we heard that Dervish were going to represent Ireland in Eurovision we decided to write a song combining an Irish flavour and a European theme, one that addressed the changing nature of both Ireland and Europe. (...) It struck me that Eurovision 2007, embracing almost all of the continent, could at last be said to represent the flowering of this promise. And that was before we learned that the Czech Republic is entering Eurovision for the very first time in 2007! This year, as well as being the 50th birthday of the European Union, is also the 30th anniversary of Charter 77, the movement that led to the eventual Czechoslovakian revolution of 1989. "They Can't Stop the Spring" is a kind of Celtic celebration of the eastern European revolutions and their eventual outcome, including the presence in Ireland of thousands of beautiful Polish, Czech, Slovakian and Latvian women!"
‘They Can't Stop the Spring' werd gekozem uit vier nummers die Dervish afgelopen vrijdag bracht in ‘The Late Late Show'. Ze zijn alle vier nog te zien en te beluisteren op www.rte.ie/tv/latelate.
