So where are these bands from?

Some definite surprises, several fuzz blasters, yikes!

Thanks PJ Dirty Water!

I followed up on your leads and after previewing a mono copy of The Sidekicks LP on RCA (1966) I'd agree with you, the album title track, "Fifi The Flea" is indeed a pile of crap;
still I did find 4 strong tracks - "Not Now" (which oddly sounds weaker in mono, to my ears), "He's My Friend", "Ask Your Friend" and "Ollie Wong" (for it's incorrectness alone, a keeper!).

Both "Friend" tracks feature solid fuzz guitar breaks and of course "Not Now" is a highlight.

The Redcoats aren't bad either, and the Dionysus reissue you brought to our attention can be audio-sampled on amazon.
The Sidekicks were from Absecon and Wildwood, New Jersey and did their 1st audition in Atlantic City.

The link you provided had a detailed bio told by the band: epic... truly epic... thanks again!

Some of the tracks have the Brit beat sound, some sound like summer of '65 Mojo Men, Beau Brummels, pretty rocking... no filler.

So The Sidekicks recorded at RCA... maybe they were from L.A. - or (like Elvis) Memphis?
Is the single in stereo? How's the flip?
