The Beach Boys were respected critically (and commercially) during the late 60s and early 70s in the UK far more than in the US. In retrospect, would it have been wise for the band to temporarily relocate their base of operations to the UK during these years? They could have continued US touring. But the close proximity to other progressive UK bands may have helped them cultivate an "aura of hip" during this period. Of course, other things like matching shirts would have to be ditched. But could this move have done anything to help them?
I realize the big problem with Brian and his illness/drug use during this time would have likely prevented such a thing on its own. But hey, this is theoretical. Debate away.
I do think this could have been a good idea, as long as the band refrained from making any UK novelty songs referencing cities, UK foods, etc. And pre-Jack Rieley, I'm not sure that would have been a resistible temptation by some member(s). Seriously!
