"Da Da Da", Trio's most significant hit stateside, is partly in German, English, and Russian. As any fan of Pitr from the User Friendly online comic would know, da is the Russian word for yes, making this song's refrain essentially the same as that of Lithium by Nirvana (as sung on the album, not as reported in JeffMagnus's writeup).
Trio also recorded an English version, which was covered by Pinocchio, a trance artist from Sweden.
