I forgot to check credits for both; but I know in the episode about the bank worker who acquired the ability to read minds, it was Dick York who was the first Darren on Bewitched; and it looked like the dude who was trying to get a loan to gamble on horse racing was played by Hayden Roarke from I Dream of Jeannie. I know that he and the other actor who took over the role of Darren had don't ask don't tell attitudes in real life. I know it was Dick Sargent, but I can't remember his birth name. When I first started watching Bewitched, it was Sargent doing it; and I got upset when I tuned in to watch it later and saw York instead.

Here's positive lyrics to the theme song narrated by Rod since the first ones I thought of weren't.

He was such a real cool guy.

Take care and God bless
