John Sidney Linnell is an American musician, known primarily as one half of Brooklyn, New York alternative rock duo They Might Be Giants. In addition to singing and songwriting, he plays accordion, baritone and bass saxophone, clarinet, and keyboards for the group.
Linnell's lyrics are perhaps most well known for their inclusion of strange subject matter and word play. Persistent themes include aging, delusional behavior, bad relationships, death, and the personification of inanimate objects. Conversely, the accompanying melodies are usually cascading and upbeat.
