In 1958 the band were part of the Dutch pavilion at the Brussels World Fair. They were the relief band. While the Hawaiian band took a break, the Tielman brothers were supposed to be on for just 15 minutes but took advantage of the opportunity. While on stage they excited the audience with their stage antics while tossing instruments to each other and playing the bass with their teeth etc. Their energetic stage performance drew the attention of international concert promoters, and the band was booked to play for several concerts in German night clubs, including on the Reeperbahn in Hamburg.
