The Sonics (!)

This mid to late 1970s pop and standards group were in fact The Sonics and were in fact descended from the solid rock beat stomping Sonics of the mid 1960s. What the fuck happened? Sonics leader Andy Parypa gave up the group and name to pop singer Jim Brady in 1968 and this group here were most certainly directly derived from Jim Brady and The Sonics. Why Jim Brady et al kept the rocking name Sonics is so mystifying.
(And yes, a big businessman in Seattle payed the rocking Sonics in 1966 for the use of their name -inspired by the supersonic jets of nearby Fort Lewis (no, not named after me)- for a basketball team. And you know the Seattle Sonics, don't you?)
