In the episode when DJ wins tickets to a Beach Boys concert, The Beach Boys aren't playing in San Francisco. They are playing in the Coliseum in Los Angeles. You can see the Coliseum pillars in a couple of the shots. Whoops!
Yeah
They never said the Beach Boys were in Las Angelas
In fact, though the Beach Boys came to their house just before the concert and gave them more passes so you got to assume they like to travel before a gig
A couple of hours from SF to LA?!?! How fast do you drive? LOL It's about 400 miles. I really doubt the Beach Boys would have driven that far (about 12 hours round trip) just to stop by the Tanner household. But, back to the slip-up at hand . . . do you expect the show to arrange for a Beach Boys concert in SF JUST for the show? Come on . . . they filmed it at a convenient concert event, which was in LA, which also is where the show was filmed.
