Not only is "Magic Colors" a cover, it's a cover of a song that failed to chart and that had its album canceled. So, if you're Teddy Robin & The Playboys, you'd likely have had to have been an extreme fan of Lesley Gore to even know it existed, unless you were connected to some producer or talent scout who's scouring America for available material. This assumes that Hong Kong did not remain a major market for Gore after the U.S. faded. In any event, she'd seem not to be the sort whom a psychedelic band — if that's what Teddy Robin & The Playboys were — would be likely to pay attention to, not even during her aborted attempts at being "with it" herself in 1967 terms.

(Gore's major impact had been back in 1963, and her sensibility and style and musical world had been wiped out by the British Invasion; if the person who posted this on YouTube is correct, the Teddy Robin version didn't come out until 1969, which was a different planet from 1963.)
