Hunter's "Box Of Rain" says these lyrics were "written to a Moorish setting composed by Mickey Hart that eventually evolved into a worldless melodic segment of Terrapin Station." That segment may be the swooping Jerry Garcia guitar line which forms part of At A Siding on the Terrapin Station CD (starting at 09.20). But this is not confirmed.
The Grateful Dead played "Terrapin Transit">"At A Siding" (instrumental)>"Terrapin Flyer" on 18 March 1977. This is listed (confusingly) in DeadBase and in the dead.net Taper's Section as "Alhambra."
L'Alhambra
Six guitars
Each plays
a different tune
Five play slowly
One plays quick
an Allegrias
in clear moon
Eight hands clap
to summon up
the Tarantelle -
Beware!
Yo no he bailado
con su hija ya
I have not danced
with your sister yet
Yo no he bailado
con su hija ya
No he bailado desde
Hay que no baile
L'Alhambra
Five guitars
play as one -
together now
One has gone
into the shadow
Gone with him
is his guitar
Six hands clap
Two are gone now
Captured by
the Tarantelle
Someone else
must play guitar
when time comes
for making love
No he bailado desde
Las Zapatas son perdidas
I have not danced
since my shoes were lost
Yo no he bailado
con su hija ya
No he bailado desde
Hay que no baile
I have not danced
with your sister yet
Is that she who
sleeps by my guitar?
