At the YouTube links below you can see two clips from an international choir competition in Prague 1996, withe Nyköping Chamber Choir performing "Napadly písne" by Antonín Dvorák, and the spiritual "Wade in the Water" in an arrangement by legendary Norman Luboff.
The picture and sound quality is somewhat poor, but still you might get an impression of the music, the choir... ...and the conductor.

Another clip me conducting the choir Polyphonia Khoros from Florianópolis, SC, Brazil. Three pieces put together from a concert with Spanish music, in May 2018.
