A five-member international jury selected the winning song 4 votes to 1 over the songs "Ik heb geen geld voor de trein" from Albert West and "Circus" from Debbie.

Solo career
Teach-In toured Europe for the next two years, but the disappointing sale of the album "Get On Board" and the song "Rose Valley" caused the band to break apart in 1978. Whilst Ruud Nijhuis and Koos Versteeg decided to reform the band in 1979 with two new female singers, Kaspers decided to continue her music career as a solo artist under the stage name Getty, recording a couple of discs including the Getty Album, featuring such songs as "Mademoiselle", "Love Me" and "De Eerste Liefde is Een Feest", originally "The Queen of Hearts" by Agnetha Fältskog in Swedish and English. Her vocals can also be heard on Rick van der Linden's "Cum Laude" album and on recordings made by Radio Veronica. In 1978, she joined her bandmate John Gaasbeek with Wilma van Diepen and formed the Balloon trio, recording a few songs such as "All You Need Is The Music" and "Summerparty", featuring cameos of well known songs. After little success, the trio broke apart in 1980.
