Lon, if I could burn you a copy of my LP, I would. That late edition of JA always sounded bloated and sluggish to me without the charm of the earlier group. Barbata didn't have a light enough touch on drums and I never did "get" Papa John Creach (w/the Airplane, that is). I'm sure he was a fine musician, but for me it never worked.
As for "Long John", same problem. I've still got the vinyl, though - including a second SEALED version. Well described by AMG: "When the LP hit store shelves in the summer of 1972, it became instantly notorious for the cover that transformed into a cigar (read: stash) box. The inner sleeve went as far as reproducing the image of tightly compressed domestic ganja, replete with sticks, seeds and stems."
