Beer Barrel Polka, also known as Roll Out the Barrel, is a song which became popular worldwide during World War II. The music was composed by the Czech musician Jaromír Vejvoda in 1927. Eduard Ingriš wrote the first arrangement of the piece, after Vejvoda came upon the melody and sought Ingriš's help in refining it. At that time, it was played without lyrics as "Polka of Modřany". Its first text was written later (in 1934) by Václav Zeman – with the title Škoda lásky ("Wasted Love").
