Another I recently found is BRAVE & THE BOLD 184 (March 1982) teaming Batman and the Huntress, in a story by Mike Barr and Jim Aparo.
The two heroes discover an apparent connection between Thomas Wayne (Batman's father) and a local mobster.

I'm always amused by these "Batman No More!" -type stories, where the hero apparently gives up their masked identity forever, and generally only sticks to that vow for a few panels, and not even a whole issue.
I especially enjoyed the opening Christmas scene in this issue.
