This info basically came from a previous thread on here regarding The Miracles "From The Beginning" UK issue - TML11031.

The track listed as "Mama Done Told Me" and released on the UK edition of "From The Beginning" [TML11031) is by Herman Willis and is called "Come On". This track [[and two others by Willis) are in the Motown Vaults but are not actually owned by Motown - though I think Motown owns the tape they were recorded on. It looks like the engineer just sent the wrong tape to the UK, and as no-one there had ever heard it, or the Miracles track, it didn't get flagged and was released. Doesn't mean it was a Motown recording, though, and even if it was, it doesn't mean Willis got a contract.
