The Happy Days Jefferson High School is the same school used for the Brady Bunch Fillmore School Correct? Notice the very recognizable arches?
I often wondered if it was a real school and what was the real name and actual location? I Loved it when they filmed outside the studio on a location (rare at that was).

I believe these are publicity photos they took back in 1975.

Yes, that is correct. Both shows were filmed at Paramount. As i recall, Lucille Ball's dressing room was located just to the right of it. I remember seeing this location on the Paramount Studios tour several years ago and that is what the tour guide told us. The Jefferson High School location was located near the Gower Street entrance and it was the divider between the Paramount lot and Desilu, when it was located next to Paramount.
