Big Dan and the Sand Dollars
Shag band playing The Pavilion at Myrtle Beach, SC in the 1989 film Shag, set in 1963. Shag is a dance done to "beach music," a style of laid-back R&B popular with drunk white tourists for decades on the East Coast. Imagine if Motown stopped all musical growth or new ideas circa 1967. That's beach music.
Played by real band The Voltage Brothers: Jim Kelly Jr., Garry Goins, John Lewis Jr., Douglas Smith, Lawrence Whitaker.
They perform "Stay," and "Sixty Minute Man."
