"It's Only Make Believe (Doctor Doctor)" by Sheila

Hailing from France, Annie Chancel took the stage name of Sheila and managed to score a single minor chart hit in the US in 1982 when "Little Darlin'" peaked at #49. Not sure why she became only a one-hit wonder as there seemed to be plenty of radio-friendly material to mine on her album of the same name.

"It's Only Make Believe (Doctor Doctor)" for example was certainly competitive enough for 1982 radio.
