I don’t recall that Odd Couple. Maybe it was a Summer replacement. Demond Wilson sort of dropped from being a high profile actor after Sanford and Son. He was perfect for that role at that time in our culture.
Demond is still alive, though.
There is a short YouTubevideo entitled; “Demond Wilson Arrives to Meet Donald Trump. Nov 28, 2016.
Demond became a preacher.
I maybe watched an episode or two of the new odd couple.
