Well, now I know what was on Side 2 of the unmarked tape: Another King Biscuit Flower Hour concert. This one is Boston, playing at Long Beach, March 19, 1977, on “Best of the Biscuit,” i.e., a King Biscuit Flower Hour rerun. I can pin down more details than usual because not only was this KBFH extensively bootlegged, but there was also a legal record release in the ’90s.

I’d apparently set the recorder up and left partway through, because it still has the ads for the second half (a couple of which are worth keeping in their own right, e.g., Ray Charles singing a ditty about Scotch brand Recording Tape), and goes straight into the following show, which was also worth keeping: “Rock Around the World,” show #169 (How weird is it that there are obsessive fan sites cataloguing Rock Around the World, but none that I’ve found for the King Biscuit Flower Hour?).

RATW #169 opened with twenty minutes of Pure Prairie League in concert on Long Island somewhere, followed by interviews with Bob Welch and Mick Fleetwood, interspersed with some of Welch’s music. Unfortunately, the tape ran out before the interview ended, so it cuts off rather abruptly. Still, I got twenty minutes of good Pure Prairie League (they were better on stage than in the studio), including a song that they never released anywhere, not even on a live album, but for which (thank heavens) they gave title and composer (“Choo Choo Charlie,” by Tim Goshorn) from the stage.

What’s kind of sad is that listening to the Welch interview, it’s clear that he was struggling with depression all the way back in the ’70s, so that his suicide in 2012 should not have surprised anyone.

Anyway, both these shows ran on WKQQ in Lexington, KY, on October 30, 1977; that’s where I got them.

While researching dates, I was startled to discover that apparently the current WKQQ-FM in Winchester is not the one I used to listen to; that one went bust, and when WLEX (which I remember and didn’t care for) moved from Lexington to Winchester in the ’90s they took over the defunct station’s frequency and call letters.

Anyway, I’ve got both shows converted to MP3 and added to my iTunes library.

So, that was the unlabeled tape. Three down, forty-nine to go. The remaining forty-nine are almost all labeled, but some of the labels are things like “Stuff” or “Mostly blank,” which aren’t very helpful.

The next one I’m going to check out, tonight or tomorrow, says “Janis Joplin ’68/70 / Jefferson Airplane 68-69,” which I suspect is all just albums I already have. However, it’s 2400 ft of tape, which at my usual 3.75 ips speed would be over four hours, so there may well be other stuff on there I do want.
