Who is the female singer who sang ''m his lady lady lady he's my man right from the beginning in the 60s or 70s?

The song is "Lady Lady" by "Cynty and the Monkeys", produced by Lee Perry. That is a Jamaican Reggae cover version. I used that information to discover that the original song was written by Eugene Record and sung by Barbara Acklin. It was a hit in 1971.
