Mind-Boggling Lead Guitar Breaks?

I think that these are beautiful:
The Squires – Going All The Way (1:45)
and Dr. Spec's Optical Illusion - She's The One (0:52)
 
I would agree that the shared version of "It's A Cry'n Shame" more than fits the bill.
I had a question.
On Garage Hangover, there's a photo of this release. and it looks to be a test pressing of the version that was (then) soon to be?
On youtube, there's a photo of this release that looks to be an acetate?
I ask because on youtube and also Garage Hangover, this version is listed as a rehearsal tape.
The short question is... is this version an acetate or a rehearsal tape?
 
Another noteworthy Pee White & Co. performance is their execution of " I Wonder Where My Baby Is Tonight" on the circa '66 NL "Tiener Band Show" live LP. And of course their go at Wooly Bully is a hoot !
 
I'll move the clock hands back and set the WABAC Machine to the 50's for some blistering RAB guitar :
