I've been a casual fan since the mid-60's and for some reason that i can't explain became a "super fan" after the announcement of this tour. have no idea why that happened.
I'm surprised you didn't get really hooked by the Endless Summer/Spirit Of America one-two punch.
That's when I became a fan - 1975. And, the next thing I know, there was a new Beach Boys' album almost every year from 1976 - 1980. That was a weird, wacky time. A lot of the concerts I saw were train wrecks, and, obviously the albums were a mixed bag. But, there was never a dull moment!
