I wonder if the dates he dated Donna (if he DID date her) are correct. He was actually MARRIED from 1977-1982 to actress Kay Lenz.

Isn't she too young to have been with 'ol Dave?

I heard years ago that even tho David and Donna went out a few times, they were just good friends. I think it was in the early 1980's.

I knew Donna Dixon and Paul Stanley were a couple. I didn't know Stanley had a cameo in "Doctor Detroit".

Totally agree - Paul Stanley - Yuck!
This positively infantile preoccupation with bosoms!Terry-Thomas about US 1963.Hasnt changed much!

Fran Dreshcer introduced Danny and Donna on that movie. Engaged to paul Stanleyyuck.
I'm not trying to be annoyingit just always works out that way.

Donna Dixon didn't just appear on the scene and marry Dan Aykroyd. In 1982, she was engaged to the guy from KISS, Paul Stanley. In fact, Paul Stanley has a cameo in the movie Doctor Detroit, starring Dan Aykroyd and Donna Dixon. It was on this movie that Aykroyd and Dixon struck up a relationship that led to her dumping Paul Stanley and marrying Aykroyd.
Her hit TV series, Bosom Buddies, ran from 1980-1982. If she dated David Cassidy it was in 1981 or earlier. It wouldn't be surprising, as she 16d0seemed to like musicians.

David did date Donna Dixon right before she hooked up with Dan Ackroyd.

There are a few photos of David & Heather Thomas together, she was once on his old tv show Man Undercover(around 1978). That could be who you saw. I am a big DC fan & have never seen him with Donna Dixon?? Oh well, just thought I'd throw that in

i never heard of a pairing of dixon and cassidy. it seems to me, she wasn't on the scene too long before hooking up with ackroyd.

Maybe you have her confused with pics of Shaun's first wife Ann Pennington. The two women resemble each other. I may be wrong but I never heard of David Cassidy and Donna Dixon having dated.
