After the demise of the Dwight Twilley Band, Twilley continued as a solo act, keeping Pitcock on lead guitar and adding Susan Cowsill on harmony vocals. This lineup released the album "Twilley" for Shelter/Arista in 1979, although the album's most successful song, "Darlin'", featured backing vocals by Seymour. Twilley's next album, "Blueprint", co-produced by Jack Nitzsche, was rejected by Arista after the failure of the 1979 single "Somebody to Love" although it was assigned an Arista release number. "Blueprint" ultimately was never released, keeping Twilley out of circulation until his Shelter contract expired at the end of 1981.
