Here in Grand Junction the Do-Wop shows are on PBS pretty often. Down in New Orleans the old 50's R&R, R&B and Do-Wop has been brought back for maybe 15 or 20 years there about.
It is really very popular and really sounds like the 50's. Maybe the name that they are calling the music helps. They refer to it as "Swamp Pop."
