Dick's / Dave's picks

I think there's a reason that sets such as Reckoning and Dead Set are on the "big, important" label and some of the soundboard stuff is available with less fanfare.  But there are some great moments on the soundboard tapes.  I was cruising through Houston with the radio on the left end of the dial a few months back and heard a mind-blowing version of New Potato Caboose.  I think the date was 8/24/68 (I could be off on the year).  I had forgotten the sort of magic they could muster at times.  Does anyone know where this track is available?

Many thanks to fourwnds and rbbert for that info.

Does anyone have any of the old vinyl on the Pig label?  I have (somewhere) one Dead concert on colored vinyl from the Pigpen days--pretty decent sound, as I recall.  There was at least one Pig LP with the Airplane live as well--I think it may have been a tv show they did.
