What Harry says here is true. Whenever anyone hears "Alley Pop" they think of the Hollywood Argyles, whose version was the "national" hit and is featured on dozens of compilations. But people in Los Angeles (those who were teens to young adults at the time) will tell you is is by Dante and the Evergreens, whose version was the local best seller thanks to heavy airplay on outlets like KHJ at the time. Until their death my parents always said they hated that "cover version" by "those Argyle guys." LoL!Everything was copycat back in those days. If a record became a regional hit in one area, someone in another area would copy it and try to have a hit with it on their own.
