From the wiki: “The original record label for ‘Shop Around’ credits Bill ‘Smokey’ Robinson as the writer, with Motown founder Berry Gordy as producer. Robinson claims he wrote the song ‘in thirty minutes’ and that it had been intended originally for another Motown singer, Barrett Strong (‘Money (That’s What I Want)‘), but that Gordy thought the song was more suited to the Miracles. Subsequent labels list both Robinson and Gordy as co-writers.
“‘Shop Around’ was initially released (as Tamla 53034) locally, in Detroit and the surrounding area, but not intentionally. Motown’s history of the song relates that after the first pressings were distributed to radio stations and record stores ‘in September 1960, [Gordy] couldn’t sleep, worried that it wasn’t good enough (‘too slow, not enough life’). He called Smokey in the middle of the night, and had him bring all the Miracles to the studio at 3 a.m. to lay down a new, slightly faster take of the song. Gordy himself played piano.’
