die lollipops has featured two singers at a time for most of its history; generally these have been girls between the ages of about 11 and 16. because the band has been around for nine years, they must replace their singers with new ones every few years. the current duet started recording in late 2007 with susi and fiona (then 12 and 11 years old respectively). they released an album called "einfach tierisch" in march 2008, and plan to release another one called "immer in bewegung" in july 2009. peter hoffmann has remained the producer since the group was formed. the band has attracted composers from other bands registered by edel music; a singer named klaus büchner had written a song about drinking alcohol called "wir feiern wieder feste" in 1987 when he was singing in his own band, called klaus &amp; klaus; he then re-wrote it as a children's song about a never-ending party for die lollipops. the title of the song is still the same and the syllable rhythms are similar, especially in the chorus.
