The Wonder Who were a nom de plume for the Four Seasons for a short period of time (66/67) during Frankie Valli's solo period in the mid sixties. A few forgettable singles, including a tepid version of Dylans \"Don't think twice it's alright\". But flipping it, we discover this \"\"Sassy\" instrumental. A classic hammond groover, popular across both scenes. On Uk Phillips from 1966.
