Question about the song, 'Cruella de Vil'

When Cruella enters her old, broken car and theadio plays, was that song the original, original, or did they hire another man who sounds just like the original Robert to sing it?

"Could things possibly be any worse?"
"Cruella de Vil, Cruella de Vil"
"SHUT UP, SHUT UP, SHUT UP, SHUT UP!"
"If--she--does..."

"Count me in. Anything to get me out of this place."
