Harry Lyon is a New Zealand musician and songwriter. He first came to prominence as a member of the band Hello Sailor after playing with Christchurch top 40 band Beam. After Hello Sailor, Lyon formed Coup D'État with Jan Preston, Neil Hannan and Steve Osborne (who was replaced by Paul Dunningham after a short time). They were awarded the 1981 RIANZ Single of the Year for "Dr I Like Your Medicine". The band split the following year. Hello Sailor reformed for the opening of the renovated Gluepot in 1985 and, following the success of the performances, began touring again.
