Reading along in PK Dick's novel Valis. Odd parallels to Henry's wacky 70s adventures.
In the novel Valis, protagonist (and author's alter ego) "Horselover Fat" [Philip = greek for "lover of horses"; Dick = german for "fat"] has strange "theophany" in 1974, sending him on a sort of time-warp quest for God, which includes contacting the rock star & film-maker "Eric Lampton" (Eric Clapton, get it?) with secret information about time-traveling Christian world-savers.
In (so-called) real life, poet "Henry" has strange theophany in the fall of 1973, sending him on a sort of time-warp quest for God, which includes traveling to London to see rock stars (& film makers) Rolling Stones (Keith Richards, in particular) with "information" about time-traveling (UFO) Christian world-savers.
(- there's also the parallel (in fate & plot) between Fat's "Gloria" and Henry's Juliet.)
PK Dick is great at evoking the period flavor...
"Horselover Fat". I may have to try to work this into the Fontegaia/Palio sequence, somehow. S.F. is already in there - but I thought it was more San Francisco than Science Fiction.
