Vonnegut was interviewed for Indianapolis public television station
WFYI's show "Across Indiana" in 1991, in conjunction with the first
Worstruck book festival there. There's links to streaming video of
archived shows (all of which require Windows Media Player), including
that one, and a drop-down menu for more recent shows (#1711 from April
featured a tribute to Vonnegut and excerpts from the 1991 interview):
