Thanks to the Facebook-Site “Skateboarding Hall o Fame” for finding that rare video from 1965, featuring italian-born Piccola Pupa on the microphone and Wendy Bull on the skateboard.
The song was also released on a vinyl 7″ the same year by DAY DELL Records (cat.nr. DD-1008) performed by nine-year-old Norma Tracey and her Cinderella Kids. According to surf music historian John Blair, Norma was the daughter of Jimmy Wisner, co-producer of this record and co-writer of that song.
Obviously there´s at least one more version by Italian singer Rita Pavone.
