Groovy Little Suzie 

"Groovy Little Suzie" by Little Richard

Harry Nilsson wrote "Groovie Little Suzie" but he admits the song is a copy of "Good Golly, Miss Molly" which was written by John Marascalco and was a hit for Little Richard.

Little Richard recorded Harry's song. The songwriting credit, however, was given to Marascalco.
