Am Anfang War Das A: 25 Jahre Sesamstrasse

Am Anfang Was Das A (It Started With "A") is the 25th anniversary special of Sesamstrasse, the German co-production of Sesame Street, from 1998.

The special stars actor Piet Klok as a rather confused professor, explaining the theories behind Sesamstrasse with the help of archive material. Meanwhile, all the Strasse-inhabitants get ready for the party.

As a surprise finale, girl rapper Blümchen (Little Flower) performs her Sesamstrasse Rap.
