The band 'Kinderlach' is coming out with a new and impressive show and the news is being celebrated with a new hit • 'When Will You Grow Up' is a kind of protest song from the same studio that brought the hits 'Only Children' and 'Leave Me Alone', which speak from the perspective of the adolescent child striving for independence and entry into the adult world • The lyrics and melody are by Eli Klein • The electronic arrangement was produced by Itzik Dadia and Shmulik Berger
