I remember in about 1965, Welti and James moved from channel 4 to 5 to join Dick Nourse. This created the Nourse, Welti, and James nightly news. This group stayed together for something like 30 years.
A side note. Paul James had been Utah’s play-by-play guy until the move to KSL. When he went to channel 5 he went on to be the BYU play-by-play guy. He did that for 35 years.
