"Mixed-Up, Shook-Up Girl" #37 8/22/1964

This falls into the "lost oldie" one-hit wonder category. In the early days of rock and roll, almost every city had its own regional style, like New Orleans, Memphis, Detroit, etc. - the British Invasion helped to do away with that. Philadelphia-based artists like Chubby Checker, DeeDee Sharp, the Orlons, Bobby Rydell and others reflected that city's genre. Here's a last vestige of Philly-style music (Camden, NJ, actually).
