Hallo Vriendjes En Vriendinnetjes or Hello, Boys And Girls, is the theme song of the worldwide known Dutch clown and acrobat duo Bassie & Adriaan performances and their long running television series.
[2] People from all over the world place themselves in front of a webcam and videotape their singing the theme song with or without the accompanying music.
From now on every performance and related event would open and end with this melancholic version, as well as the shorties produced for Belgian television and the tenth season "Liedjes Uit Grootmoeders Tijd" (Songs From Times Gone, 1995).
For the CD and Cassette release of the series' soundtrack "De Reis Vol Verrassingen" (The Journey Full Of Surprises) a remix in Caribbean style was produced as opening song.
For the remastering of the complete series in 2003 one new version was made for (almost) all television seasons, played on instruments including the flute.
