(Larry Williams, Venice Musi BMI)
The Sentinals made a couple of albums for Del-Fi in 1963-64 and achieved a good deal of regional popularity, although only drummer Johnny Barbata (later in the Turtles and Jefferson Starship) would go on to name groups. They formed in 1961 in the Californian Central Coast town of San Luis Obispo.
