Yeah, it's "At The Hop"
The song, Do The Bop, was co-written by Dave White, a member of Danny And The Juniors, for the dance craze on American Bandstand, The Bop.
After hearing the song, Dick Clark suggested they change the name to At The Hop. With only a piano, bass and drums the group recorded the song in about an hour.
"At The Hop" by "Danny And The Juniors" is a rock and roll classic now.
