Good one, slowpoke! That's Tell Him, by The Exciters. I won't say how old (young?) I was at the time, but I remember it well.
I think this one may even have been a few years earlier:
I searched everywhere
Just to find someone who cares
They came down to interrupt
Just as I had given up
(BTW, the original 1961 version of Dedicated To The One I Love was done by the Shirelles.)
