France's Garage Psychiatrique Suburbain (more here) never topped this slightly twinkie but still utterly rollicking barrage of melodic hooks and underwatery keyboards.
G.P.S. - Panique Sur La Plage (1985)
Respect must be paid to the heroic ModPunkArchives for championing the by now unfortunately-initialed G.P.S. on their pages.
By the way, singer Thiery Hazard later gained pop celebrity in France for an intermitenly pleasant eighties take on late-sixties psych-pop, as heard (and seen) in songs like the toe-tapping Poupee Psychedelic and the Robert Palmer-esque Le Jerk. Hey, it could be Mitsou!
Panique Sur la Plage 7"
Here's a MySpace page but I believe their sole CD is out-of-print.
