Here's one on ebay right now:

Hard to say if it's a boot or not but my guess from the tracklisting is that it's just (yet) another repackage of the "London live '68" set so by rights they shouldn't have used a FM picture on the cover with DK in it as he's not on the recording. You're better off sticking with the version that's already out there. You might like this if you liked "Live at the Marquee" as it's got that same grumbly "microphone in the hall" sound quality (though John is on bass on this one and not Bruns since this is apparently from a 4/68 show from an unknown London venue).
