This one a split single with two French garage bands from Toulouse. Sadly I don't have much biographic details about them. Both sides are wild garage, but the Space Beatnik's one features a saxophone.
The Shoo Chain Brothers were most of the time between six and eight people. The only time I saw them rehearsing they had three guitars and a violin, too! But that's not obvious when you listen to their side.
They took care from the details: the EP is on Zombie Dance Records, catalog # FUZZ 001.
The problem with a lot of french singles is that the label stays a standard one.
The Space Beatniks issued soon after a picture disc single that I've never seen nor heard, while the Shoo Chain Brothers seems to have vanished in the haze…
