Really? Okay, there certainly is some overlapping material with "Gas Mask" on Weasels and "King Kong" on "Ahead of Their Time". I just now checked out the setlist for the RFH show in 1968 and it does seem that these improvisations did indeed take place as part of the "King Kong" monstrosities. So it wasn't necessarily a cut-and-paste tape edit on FZ' behalf (but the improv bits on "Transylvania Boogie" most certainly were). And it also appears that "Ahead of Their Time" blends early and late shows into a monolithic concert album: the Lumber Truck Medley is from the late show, everything else from an early show.
However, it is a bit weird that "Help I'm A Rock/Transylvania Boogie" do not appear in the Zappateers setlist for the Festival Hall show. I don't know if there's a tape cut for the early show, so another explanation that I can muster is that the combo appeared on the late show, but were unrecorded by the bootlegger.
As far as I know Ahead Of Their Time breaks down as follows:
beginning through partway through the Ian/Roy dialogue section - late show
second half of Ian/Roy through "King Kong" ("Gas Mask" section) - early show
"King Kong" (end) through "Transylvania Boogie" theme - late show
"Transylvania Boogie" (ending percussion solo section) through "Sleeping In A Jar" - early show
OCLT Medley - late show
For the late show we don't have an unofficial source, except for a few songs in an early mix/edit from FZ ("Uncle Meat," "In The Sky" and the same performance of the OCLT Medley).
