Career
Plummer played what is termed the plectrum style of banjo playing and used, amongst other instruments, a Vega Vox 4 plectrum banjo as well as a Jerry Reilly Bicentennial Electronic (manufactured around 1976), which used as its base a 1927 Gibson Mastertone rim. He played this particular instrument, which was heavily ornamented in the casework and glowed beautifully under lights, for some of the shows he did with Liberace. Another source also suggests that he played in the Eddie Peabody style.
He also toured with country singer Eddy Arnold and was also often a guest on television specials, particularly the 1975 Disney production Welcome to the World, starring Lucie Arnaz (when he was just 14 years old) and later in 1980, on Lucy Moves to National Broadcasting Company, starring Lucille Ball, Bob Hope, Gene Kelly, Donald O"Connor and a host of others
He recorded an LP in 1974 released as Banjo on the Roof on the Audio Video Interleave label, also reissued on other labels. Plummer was posthumously inducted into the National Four-String Banjo Hall of Fame.
