In 1980 Frank was approached by the Leuven pop / rock band Interface, who was looking for a new singer. It became a very fun and instructive period with many rehearsals and a number of performances, in youth centers and in different prisons. In 1983 the first single from Interface, titled 'Memories', was released. In 1984 there were some notable performances and participation in the 'Rock Rally' in 't Stuc in Leuven. More performances followed and in 1988 Frank wrote the song ' Think about it ! In June 2000, Frank was sent by the Christian church Emmanuel in Haacht to take part in a special conference in the US for singers and musicians. The Brownsville Worship & Intercession Conference took place in a large church of Assembly of God in Pensacola, Florida. In many ways it was a special and instructive experience and an incentive to use our own talents even more and better. Frank has been available since 2000 to provide musical support for both Catholic and Protestant celebrations.
