In 1997, it was announced that the original line-up of Teach-In, including Kaspers, had re-recorded some of their old hits and had plans to tour again. The band reunited to sing "Ding-a-dong" at a show in Maastricht on 31 August 2007. Kaspers also performed with the group in the original line-up at the opening of the 2009 Eurovision Song Contest in Moscow, singing classics such as "Ding-a-dong" and "I'm Alone".
