Plonky

They both possess a light, slightly nasal voice, but whereas Siffre has his excellent guitar work to back up his vocals, O'Sullivan only has that same old plonky piano and his arranger.

Clement Ishmael's plodding arrangements for lone, plonky piano, and the unlovely voices of two-thirds of the cast, do not help: even a sublimely sexy song like You Can Leave Your Hat On is rendered flat and toneless.
