2nd song: Tijuana

I always loved the Travel-log album, and Tijuana is a great song!

To me the song sounds like your "fake flamenco 101" of playing the open E major chord 022100 and then going a fret up to 033200, which is Fmaj7(b5). Playing the "opening the full fist of fingers" strum with fingers makes this sound like poor man's flamenco. To play a flamenco solo on top of it, it's important to play E and F and Ab and A, as these notes a fret apart, played boldly gives the flamenco sound.

But back to JJ.... looking at the video on youtube:
Tijuana live
I think you can just play E and F back and forth... sounds good like that too. He plays both the barred F and not barred F at the 1st fret.

Anyway... the youtube version looks to be just those two strummed chords and nothing else really happening guitarwise. In the intro he is basically picking through the chords, to make a sort of an intro.

The solo is E minor pentatonic. For me it sounds like B-string 5th fret, 8th fret, 12th fret and 15th fret. But by the vid, he clearly is playing the Em pentatonic 1st box up on 12th fret:
e:12---15-
b:12---15
g:12--14--
d:12--14--

Will have to really listen to the original again. I actually only have it on LP, plus live versions on the Collected 3CD set and in some bootlegs.
