It appears that Richard (if that's what he said on his show) "may" have been incorrect on this occasion.
Here is some stuff I found and sadly he passed away only a couple of years ago.
"Maybe you know him as Arthur Robinson of the Doo Wop groups, The Romancers and The Ad-Libs.
Or maybe you know him from the Van McCoy label, VANDO, as Art Robins.
If you know him by any of those names, you know he has a powerful, honey voice.
Or maybe you are a family member or friend and simply know him affectionately by his nickname, Peter Rabbit.
Thearthur Robinson Thearthur Robinson, Arthur Robinson, Art Robins Born in South Norfolk County (which later became Chesapeake), and raised on Liberty Street there, 17 year old, Robinson left the Tidewater area in 1956 to seek better opportunities up North.
He landed a job at a Staten Island hospital doing maintenance. One day while sweeping, singing to pass the time faster, he was heard by a young woman whose brother was in a Doo Wop group. Soon, a meeting was set up and next thing he knew, Thearthur Robinson from Virginia, was in a New York singing group called, The Romancers.
The Romancers featured tight harmonies and soaring vocals, with several members taking turn singing lead. The group had a series of songs recorded on Palette Records. (These Romancers were an East Coast group not to be confused with a West Coast group of the same name during the same period or another East Coast group which later became known as The Dreamers).
Eventually, Robinson found himself with The Ad-Libs, a singing group which had been surviving off a hit record, “The Boy From New York City.”
The new Ad-Libs were on AGP Records and consisted of Arthur Robinson, Irene Baker, Hugh Harris, Rose Myers and David Watt. Also joining the lineup was Chris Bartley. The group got involved with a highly talented and prolific writer/producer by the name of Van McCoy.
Arthur Robinson was chosen to sing the lead on the remake of a ballad by a former member of The Flamingos, Tommy Hunt, titled, “Human.” "
