The most obvious would be Fontella Bass 'Rescue Me' which was designed by Chess to sound like Motown. Also Impressions 'You've Been Cheatin'', Bob Brady 'Everybody Going To A Love-In', gosh there must be thousands! Copying a hit style, be it Motown or James Brown or whatever, is an integral part of US Black music, and without it....Well you wouldn't have small label non-hit Motown soundalikes . Oh, that's Northern isn't it?
