Revenge Box Set Nights of Destruction

Does anyone know the source of the 3 tracks on the 6th CD in the Box from revenge? They are Ive Got Nothing, Search and Destroy and Cock in my Pocket. they are live tracks and are not the same as those on Metallic KO. They sound like they are all from the same source, the same kind of quality as the Whiskey recordings. Given Ive Got Nothing is there that must be from late 1973 or early 1974.

The revenge box is pretty good sound and the sources of the other tracks are pretty obvious. I think the first five CDs were released either as records or CDs on thier own prior to the box but that CD 6 was unique to the box.

They're from the Latin Casino gig that's also on 'Double Danger'.

double danger is probably the only show Raw Power (Academy, Latin), which I do not LOL...

otherwise the quality is a little better than Whiskey a Go Go
