My feeling is that there is no Berkeley tape (at least not in the Ginsberg archive) and that faulty memories may be at work. There are three tapes in the archives, and all are accounted for - San Francisco concert, San Jose concert, and San Jose "fan interviews". Assuming these reels are the original tapes and Ginsberg didn't copy them or compile them in some fashion (why would he?), and that the reels were likely 1200 feet in length, there would be space for just over 2 hours (128 minutes to be exact) of content if the machine were set for 1 and 7/8 ips. That speed setting would help explain why these tapes don't sound better than they do. The concerts, with the backstage material, both run close to two hours. There's nowhere for the fan interviews to go, except on to a third reel. And I'd wager that Ginsberg took off the "fan" reel, recorded the San Jose show on a fresh reel, and then went back to the "fan" reel for more recording after the show. So did Ginsberg tape Berkeley, as Pickering remembers? If he did, he apparently didn't tell Dylan, who is clearly seeing the new tape recorder for the first time backstage before the San Francisco show. Again, if he HAD taped it, even without telling Dylan, wouldn't he THEN tell Dylan before the San Francisco show? Why wouldn't Ginsberg play Dylan part of the Berkeley tape when Dylan wants to hear how the recorder captures music, and mentions how he'd like to hear how HIS band sounds on the recorder (hence Ginsberg taping SF)? That's my figuring anyway, for what it's worth.
