Well, perhaps we need to parameterize the discussion a little
bit... Let's just say, during the years, 1967 - 1980, living
in the U.S.... the best bands were British... and the best
solo acts were Americans... Hmmm...

I would agree with the "band" portion of the statement.
In fact, I used to play a little game to prove my point.

You name me a great American band from that era, and I would
name the better british counterpart. Ready? It would go
something like this:

Aerosmith -- Led Zeppelin
ZZ Top -- Black Sabbath
Boston -- Deep Purple
Doors -- Yes
Jefferson Starship -- Pink Floyd
Rolling Stones -- Beatles

( lol ... hopefully, you get the point... )

As for individuals though, I think the Brits still get the
edge...

Billy Joel -- Elton John
Iggy Pop -- David Bowie
Bob Dylan -- Chumba Wumba

my brain is fuzzy ... can't think of much more...
